✦ Synopsis

We report the LIF spectrum of the C 'lI( u' = 1) CX 311( Y" ~0) transition in the AlN molecule. Laser vaporization in combination with supersonic expansion and laser-induced fluorescence are used to produce and detect the AIN molecules. The mole0 ular constants and electronic lifetimes of the C state are determined. Predissociation and an accidental perturbation are discussed and compared to an ab initio potential calculation of the electronic states.

The A 1 P -X 1 S / system of the PN molecule has been reexamined via high resolution conventional spectroscopy, at higher rotational J-values than those in previous studies. It is shown that perturbations occurring in the A 1 P (£ Å 0 to 3) levels give access to information concerning the (e 3 S 0 ,
