Infrared absorption spectra of CO in the region of the first overtone have been observed in dilute (approximately 1 to 10 parts in 1000) liquid solutions of oxygen, nitrogen, and argon, and clear crystalline nitrogen and argon matrices. The overtone

A reaction mechanism and a correlation diagram argument are presented to account for the high photon yield of the chemiluminescent reaction of Ba atoms with N2O. Most BaO molecules appear to be formed initially in the long‐lived a3π state and to b

Laser‐photoluminescence studies of Rb2 indicate that the C 1Πu state of the molecule is strongly predissociated. Both fixed frequency ion lasers and a tunable cw dye laser have used been to excite the photoluminescence at pressures from 1 to 100 t

High resolution (0.09 eV) UPS spectra have been obtained of condensed films of N2 and CO. All spectral features are broadened by ≳ 0.6 eV upon condensation. The origin of this broadening is discussed. The difference in linewidths for all equivalent

Photon yields for the reaction of Ba with N2O are determined by observing chemiluminescence from flames in a rapid flow of buffer gas. The yield for BaO A−X photons is strongly dependent on inert‐gas pressure and is measured to be 20% at pressure

Strontium atoms were reacted with N2O, O3, O2, NO, Br2, Cl2, and F2 in a flow system to produce the diatomic oxide or halide. Photon yields were measured from these reactions in a bath of argon at pressures of 1.1–9.5 Torr. Photon yields in excess

Diatomic barium monohalides (BaX) have been produced in the gas−phase reaction of Ba, entrained in a flowing inert carrier gas, with F2, SF6, Cl2, Br2, and I2. Bright green chemiluminescent flames were observed at pressures from 0.1−10 torr. Emis

Lifetimes, self-quenching, and vibrational and rotational energy transfer cross sections of individual rotational levels in the B 3 ∏ + u state of I 2 were measured by observing the correlation between fluorescence photons and the pulsed excitation

Laser induced photoluminsecence spectra of ZrO trapped in Ne at 4 K have been obtained. Continuous wave tunable dye and cw argon ion lasers were used to excite ZrO from the X 1Σ+ ground state to the e 1Π and B 3Π electronic states, respectively. R
