✦ Synopsis

Collisional deactivation processes of the CO* A 2TI( u= I ) state are investigated by a time-resolved laser-induced fluorescence technique.Theoverallquenchingrateconstantsaredeterminedtobe (9.lfl.O)xlO-", (1.3~0.1)~10-", (1.1~0.1)~10-9,

(1.9+ 0.1 )X 10m9, and (1.5 kO.1) X 10m9 cm' molecule-' s-', for collisions with He, Ne, Ar, N2 and CO, respectively. From the dispersed fluorescence spectra recorded, it is found that collision-induced vibrational deactivation occurs in collisions with Ar, Nl, and CO, and that this process is more effkient with these quenchers than with He.

Collisional deactivation rate constants of CO+ A 'fI(v=O and 2) by He, Ne. Ar, N,, and CO have been determined by using a time-resolved laser-induced fluorescence technique. The results were combined with the previously determined Y= 1 rate constants to obtain an interesting u dependence of the rate

The charge transfer reaction of He+ with N20 produces vibrationally excited N:(X) ions. The relaxation processes occurring after formation of the NC (X, u" ) ions have been investigated. Charge transfer with N,O is the main relaxation mechanism and its rate does not vary much with the internal energ

The pressure-induced shifting coefficients for He-, Ne-, Ar-, Xe-, N 2 -, and O 2 -broadened lines of CO in the fundamental band have been measured by using a Fourier transform spectrometer. The lineshifts have been determined from the wavenumber differences between the lines of pure CO at low press
