AbstractWe observe in photoconductivity (PC) measurements EMT-like excited states of the pseudodonor CrB, which are responsible for the capture of free electrons due to their short lifetime. The energetic position of the ground state can be located at Ev + (292 ± 5) meV. A finestructure of the (CrB)° transition consisting of at least 15 components is observed in PC and high-resolution Fourier transform photoluminescence. In acceptor-free silicon a step in photoconductivity at 205 ± 10 meV is ascribed to interstitial Cr, whereas a second step at ~ 425 meV could be due to substitutional Cr.

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.

High-resolution Fourier-transform infrared spectra have been recorded and analyzed for the ν4 ν5, and ν6 fundamental bands of trans-HONO, and for the ν4 fundamental of cis-HONO. The spectral resolution was better than 0.01 cm−1, and the rotational structure has been analyzed to give improved ground-state and excited-state rotational constants, with a standard deviation of the fit to the observed line positions of around 0.0006 cm−1. Two Coriolis interactions have been analyzed between the ν5 and ν6 bands of trans-HONO.

A high-resolution infrared emission spectrum of InF was recorded with a Fourier transform spectrometer. A total of 2664 rotational lines from ν = 1 → 0 to ν = 12 → 11 were measured for the major isotopomer 115InF and 179 lines for ν = 1 → 0 and ν = 2 → 1 for the minor isotope 113InF in the X1Σ+ ground state. Revised Dunham Yij constants for each isotopomer as well as isotopically invariant Dunham Uij constants are reported. Also, an effective Born–Oppenheimer potential was determined by fitting the data directly to the eigenvalues of a parameterized potential.
