We have observed the negative ion photoelectron spectrum of the methylnitrene ion, CH3N−, and measured the electron affinity of methylnitrene, EA(CH3N)=0.022±0.009 eV. In addition to detaching the methylnitrene anion to the ground state of CH3N(X

The binding of a molecule within a cluster may be determined within the context of a simple statistical model from the measurements of cluster evaporative lifetime and average kinetic energy release. If the final product density of states is approxim

The A←X absorption spectra of NH3 and ND3, recorded in a cold molecular jet, are presented. Vibrational band progressions resolvable up to v’2=14 appear. No other vibrations are present, either alone or in combinations. Relative band intensities

Potential energy, electric dipole moment, and electronic transition moment surfaces have been calculated for the A and X states of NH3 from CASSCF and CEPA electronic wave functions. Anharmonic vibrational term values, Franck–Condon factors, and A

We report the first observation of the (0,0) and (0,1) vibrational bands of the weak, spin forbidden a 4Σ−–X 2Π transition of the CF radical. The spectra, obtained in a flowing afterglow, yield values for T0, B0, and r0 of the a 4Σ− state of

The photoelectron spectra of the negative ions Co− and Ni− have been obtained with a fixed frequency cw ArII laser (488 nm). The electron affinity of cobalt is found to be 0.662±0.010 eV, while that of nickel is 1.157±0.010 eV, in excellent agr

With a fixed-frequency Ar ion laser, the photoelectron spectra of the negative ions Fe-, FeCO-, Fe(CO)r-, Fe- (CO)3-, and Fe(C0)4- have been obtained. The electron affinity of iron is found to be (0.164 & 0.035) eV while the electron affinities for o
