Paper Abstract

Aldehydes are of great importance for the atmospheric photochemical processes. The direct usage of fluorescent method in the polluted atmosphere enables us to measure the concentration only of the aldehydes products since their spectra are covered. The separation of aldehydes is possible if the method of photofragments of spectroscopy is used. The proposed approach is based on the different dependences of COH-radical photodissociation rates for various aldehydes on exciting wavelength. In order to find the dependences the calculations of the low excited electron states of formaldehyde, acetaldehyde, and the vibration structure of these molecules were made. Thus the obtained data were used for calculation of the dissociation rates.
