PresentationsLight-induced dispersed vibrational IR-emission: a new technique to study molecular statesInstitute of Cell Biophysics Russian Academy of Sciences, Pushchino, Moscow region, Institutskay st.3, 142290 Russia; Phone: +(4967)739393; Fax:+(4967) 330509, Olga_degt@mail.ru Infrared Emission Spectroscopy, technique rarely applied in the past. Most of previous studies were carried out on gases or condensed phases by heating the specimen to a high temperature by means of electrical heating element. By using of FT-IR technique we developed a new approach of light-induced infrared emission spectroscopy, which is a method based on generation of infrared radiation in the absence of sample heating. The emission spectra were recorded during steady state illumination with visible light with a power of 10- 450 mW/cm2. The IR-radiation usually was trapped from a front surface of the sample. Some interesting features of this method are: There is promise that this nonlinear IR method will have important application in determining the structure and dynamics molecules. We plan to discuss it in our presentation.
