The emission spectrum of the AsS radical, excited in a quartz tube by a 2450 MHz oscillator, was photographed on a high resolution spectrograph from 2450 to 6900 Å. Seven bands around 6000 Å showing clear rotational structures were chosen for the first rotational analysis of the AsS spectrum. The bands were found to arise from a 2Π3/2–2Π3/2 transition. The rotational and vibrational constants of the two states derived from the present work are consistent with the previous vibrational analysis of the A′2Π3/2–X2Π3/2 system. The constants of the upper doublet component of the ground state, X2Π3/2, are ωe = 562.40 cm−1, ωexe = 2.02 cm−1, re = 2.0216 Å; the constants of the A′2Π3/2 state are ΔG′(1/2) = 403.37 cm−1, ν0,0 = 18 621.21 cm−1, re = 2.2500 Å.

Fourier Transform Spectra

The analysis of two parallel absorption bands of NO2, at 13 400 and 13 200 cm−1 respectively, has been performed using high resolution Fourier transform spectra. This paper is an extension of the work performed on the 7390 Å band (13 500 cm−1) in 1977 by Hallin and Merer, and completed in 1980 by Perrin, Camy-Peyret, Flaud, and Luc.The lines involving the Ka = 0, 1, 2, 3, 4 stacks for the 13 400 cm−1 band and Ka = 0, 1, 3, 4 for the 13 200 cm−1 band have been assigned and considerable spin–orbit and/or Coriolis coupling induced transitions have been detected.The 13 400 cm−1 band can be considered as belonging to the [Formula: see text] electronic transition, while the 13 200 cm−1 band might be, as the 7390 Å band (at 13 500 cm−1), a transition within the ground state manifold which barrows its intensity through vibronic coupling from the 13 400 cm−1 band. Tentative vibrational assignments are given.

A high-resolution study of the rotational Raman spectra of cyclopropane and cyclopropane-d6 has yielded the values 0.66962 ± 0.00020 cm−1 and 0.46079 ± 0.00015 cm−1 for their ground-state rotational constants. From these values the C–C internuclear distance is determined to be 1.514 ± 0.002 Å.

The η bands of SiF, in the region 3300–3400 Å, have been photographed in emission at high resolution. A detailed rotational analysis has shown that these bands represent a 4Σ−–2Πτ transition. The lower state is the ground state of the molecule. The principal rotational constants of the upper and lower electronic states in cm−1 are as follows:[Formula: see text]A discussion of the electron configurations is also given.

Rotational Analysis

The 2491 Å electronic transition of nitrogen dioxide has been photographed in absorption under high resolution and a rotational analysis of the (000) ← (000) band carried out. The analysis is consistent with the upper state belonging to the C 2v point group and having 2 B 2 electronic symmety with an N—O length of 1·314 Å and an ONO angle of 121°2'. The N—O length is considerably greater than the ground-state value of 1·197 Å and the ONO angle is somewhat less than the ground-state value of 134° 15'.
