HF is produced vibrationally-rotationally excited in the gas phase systems F + CH 4 and F + CH2F 2. The nascent vibrational distributions observed by IR chemiluminescence for the primary hydrogen abstractions are NI:Nz:N 3 = 30 : 58 : 12 and 36 : 45 : 19 respectively, in fair agreement with publishe

✦ Synopsis
Emission spectra have been obtained during the gas-phase reaction of F, with CSa on substitution with carbon-13 and sulfur-34 in effort to ascertain the identity of the emitter. Absence of any measurable shift in the vibronic bands on substitution with carbon-13 suggests that carbon is not present in the emitting molecule and that the previous assignment should be discarded. The measured vibrational frequencies and their shifts on isotopic substitution with sulfur-34 are nearly identical to those that have been reported previously by other workers for the ground electronic state of SF*.

A novel emission spectrum extending from 5500 to 8600 A has been observed during the gas-phase reaction of F2 with CS2. Long progressions in the lower-state (presumably the ground-state) bending frequency and shorter progressions in a ground-state stretching frequency were observed. A partial vibrat
The product polarization for the beam-gas chemiluminescent reaction ,Ca( 1 So) + F2 ~ CaF(B 2 E+) + F is found to be vary by more than a factor of two over the B-X band system. This reveals a strong dependence of CaF(B) state alignment on vibrational level.
