We have mvestigated the ennsnon of a CO2 molecule isolated m an Ar matnx at 4.7 K III the spectral region between 350 and 5.50 nm Thus emission 1s a contmuum with a bfetime of 570 ms. We assign It to the transition from the lowest trlplet state (bent) 'B2 to the fundamental state (lmear) 'xi\_
UV photoelectron spectra of matrix-isolated and condensed CO and Nz bake been measured. The emission from the 40, 1~ and So orbit& show similar relauxtron shifts of about 1 eV This shift is 0.3 eV larger for the species isolated in xenon matrices. The width of the pe&s is sm&er by 0.3 eV in the Se m
The complex W (CO) 5 ( C02) has been observed in the gas phase by time-resolved infrared spectroscopy following 355 nm laser photolysis of W (CO)6 in the presence of CO,. The complex was shown to be in equilibrium with its precursor W (CO) s at room temperature and the bond energy for binding of CO2
