✦ Synopsis

Fourier transform laser-induced fluorescence of CNN, A 'II+% 'Z-, in an argon matrix has been investigated. Eight new vibronic transitions have been found, indicating that the ground-state asymmetric stretch is 1419 cm-', about half the 2847 cm-' value of earlier studies. Reanalysis of the isotopic data of Milligan and Jacox shows that CNN is similar to its isomer NCN with respect to vibrational frequencies and force constants. The new force constants indicate that CNN has CN and NN double bonds and as one of the double bonds breaks the other becomes stronger.

A study of irradiance fluorescence spectrum induced by 476-nm laser line of an Ar(+) laser is presented for the B(1)Pi(u)-X(1)Sigma(+)(g) system of Na(2) molecule. A calibrated halogen lamp was used to calibrate a diode array spectrograph. Measured intensities are in agreement with calculated intens
