Abstract: IR multi-photon dissociation (IRMPD) of trimethyl phosphite has been carried out by a TEA CO_2 laser. The fluorescence spectra near 326 and 520 nm were assigned to electronically excited PO~* and HPO~* radical respectively. Sample presure depen-dences of fluorescence intensity were measured. Possible mechanism was suggested.
