Dr. Raúl Cetina Rosado


Dr. Raúl Cetina Rosado got his BSc. in Biology and Pharmaceutical Chemistry from the University of Yucatan in 1943, with Honorable Mention, given for his thesis as for his desertion in the professional exam. Later, he joined the National Autonomous University of Mexico (UNAM) in order to make his PhD. studies, the ones ended in 1959 with Honorable Mention

In 1954 he joined as researcher the Institute of Physics of the UNAM, position he held up to 1957, year when he enrolled in the Institute of Chemistry of the same University.

In 1961 he made his post-doctoral studies at the University of California, in Los Angeles, under the direction of Professor Saul Winstein. In 1962 he participates in an intensive course about quantic chemistry, in the University of Florida, with duration of 2 months. The concepts and applications of this subject motivated him in such a way that he starts in 1963 a series of courses about quantic chemistry at the School of Chemistry and at the Research Institute of Biomedics of the UNAM.

Probably these are the first precedents of a formal course of this subject in Mexico. Once he was enthusiastic about this area, decided to take a sabbatical year in the CNRS of France, under the direction of Raymundo Daudel, becoming an expert in the applications of quantic mechanics applied to chemistry. As a result of all this learning became the first publication in this field in Mexico with the title “Etude de la force basique de molécules organiques conjugues des état électroniques singulets et triplets”. After this date his vocation as a trainer of human resources of high level shows with the direction of the first three doctoral theses in Quantic Chemistry in the Institute of Chemistry.

In fact, his vast academic career starts in 1941 in Ciudad del Carmen, Campeche, to be continued at the University of Yucatan and later on in Mexico City; firstly, at the National High School of the UNAM and later in various schools from the same University. His lectures enjoyed of a prestigious reputation for the excellent communication of knowledge, the clarity of their statements, the clear presentation of the examples and the constant search for ways of presenting, in the simplest way, the most complex concepts.

Thanks to his prestigious recognition as a teacher, was invited to elaborate the study program of the BSc. and MSc. In Chemistry of the Metropolitan Autonomous University, at the same time that he organizes the Chemistry Department at the Campus Iztapalapa from the same University. In the same way he organizes the School of Chemistry at the Autonomous University del Carmen, with a commission granted by the Coordination of Scientific Research, with two bachelors’ degrees: Engineering of Development and Food Process, and Engineering of Development and Petrochemical Processes.

His undoubted and renewed interest in the training of professionals and specialists was manifested by the large number of theses directed: a total of fifty-six, of which forty-eight were to get a Bachelors’ degree, four to get a master and four doctoral programs. Several of the theses that he directed belong to students from universities in various states such as Puebla, Yucatan, Veracruz, Zacatecas, Jalisco, Nuevo Leon, and Baja California, among others. Many of these students give lectures at their universities. His concern to train new researchers was manifested when he trained five researchers working independently.

Among the relevant academic positions he held at the UNAM are the following: Professor Member of the Technical Board of the School of Chemistry, first in the area of Physical Chemistry (1965-1969) and then in the area of Advanced Studies (of 1969 to 1999). He was also a member of the Regulatory Commission of the Center for Materials Research in 1975, and from 1994 to 1997.

He was Director of the Institute of Chemistry, a position he held from March 1975 to March 1981. Under his direction were obtained internal and external accomplishments that led to the improvement of the Institute. He was also Head of Department of Physical Chemistry from the School of Chemistry of the UNAM from 1986 to 1990 and Head of Department of Institute of Physical Chemistry from 1991 to 1999.

Outside the UNAM he got various administrative responsibilities; in 1971 he was responsible for the Committee of Chemistry of the National Institute of Scientific Research, Institution that gave origin to the National Council of sciences and Technology. He was Technical Secretary of the same Council from 1972 to 1973 and member of the Chemical Sciences from 1972 to 1975. In 1974 he was Secretary of the Academy of Scientific Research. He served as Coordinator of the Chemistry Section of the Department of Physics and Chemistry of the Metropolitan Autonomous University.

Dr. Cetina gave 33 courses, 28 conferences and 2 seminars, in Mexican academic forums and abroad as well. His legitimate concern to establish academic liaisons with diverse institutions was manifest in that most of his courses, conferences and seminars have an interdisciplinary character, pointing at the application of thermodynamics, statistical mechanics and quantic chemistry in the chemistry and biochemistry. He had a relevant place within the teaching of fundamental chemistry. Subjects such as quantic chemistry, thermodynamics, statistical thermodynamics, chemical kinetics and physical chemistry in general, as fundamental as difficult to be transmitted, were topics he always made them simple to understand.

He was a speaker in fifteen congresses and symposiums, held in Mexico and in other countries, which were later published in the respective memoirs.

Three Societies saw him as a leading member, the Association of Professors of the “Universidad Nacional Autónoma de Mexico”, the Mexican Academy of Sciences and the International Society of Quantum Biology. He was nominated by the latter one to join the Board.

Dr. Raul Cetina was granted with various awards. The INIC gave him in 1970 a plaque for his work in this institution. He was only speaker in plenary sessions at conferences in Zacatecas, Mexico and Ciudad Trujillo, Peru. For this outstanding work the Honorable Provincial Council of Trujillo, Peru, awarded him with a diploma as a Distinguished Guest of Honor, on his visit to this city. In addition, the Autonomous University of Sinaloa gave him a diploma in gratitude for his outstanding participation in academic activities that were carried out on the occasion of the centenary of its foundation. In 1976, he obtained the degree of Doctor Honoris Causa of the University of Yucatan. In 1985 he received the National Award Andres Manuel del Rio in the Teaching area, awarded by the Chemical Society of Mexico. In March 1993 the National Autonomous University of Mexico awarded him the appointment of Professor Emeritus.
