Abstract
The vibrational relaxation of the ν1 symmetric stretch mode of N2O was studied at room temperature following an overtone excitation via a DF laser. The ν1 and ν3 (asymmetric stretch) fluorescence at 7.8 and 4.5 μ were, respectively, monitored as a function of time. A V–V equilibration time constant of 0.062 μsec⋅atm between the ν1 and ν2 (bending) modes was measured. The vibrational relaxations out of the ν2 and ν3 modes were measured to be 1.3 and 2.1 μsec⋅atm, respectively, with good agreement compared to previous measurements reported in the literature.Keywords
