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.

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.

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'.

The ν4. vibration–rotation bands of benzene and benzene-d6 have been recorded with high resolution. The K = 0 subbands have been analyzed and spectroscopic constants for both vibrational states have been calculated. Assuming D6h symmetry for the molecules the bond lengths have been determined from the ground state rotational constants of the two isotopic molecules. The values obtained are: r0(C—C) = 139.64 ± 0.02 pm and r0(C—H) = 108.31 ± 0.13 pm.

Fourier transform spectra of the ν2 band of PH3 have been remeasured with 0.0045 cm-1 resolution. Ground state combination differences from these data have been fitted simultaneously with the microwave and submillimeterwave data to determine the ground state spectroscopical parameters of PH3 including the parameters of the Δk = ± 3n interactions. The correlation between the latter parameters has been discussed from the point of view of the existence of two equivalent effective rotational operators which are related by a unitary transformation. The ΔJ = 0, +1, ΔK = 0 (A1 ↔ A2, E ↔ E) rotational transitions in the ν2 and ν4 states have been measured for the first time by using a microwave spectrometer and a radiofrequency spectrometer with acoustic detection.

The fine structures of three of the β bands of PO which occur near 3200 Å have been analyzed. The analysis shows that the upper state of this band system is a 2Σ and not a 2Π state as previously believed. The rotational constants of both electronic states have been determined and it is found that the ground state constants, previously determined from the γ bands, are incorrect.
