The (1–0), (2–1), and (3–2) infrared vibration–rotation bands of the X2Π ground state of sulfur monohydride were observed in emission from a furnace. Multiplet splitting produces two subbands, each of which exhibits lambda splitting. The band heads were observed for the first time, 285 lines were measured, and a calculation of lambda-doubling parameters was made. The spectrum was recorded using the Fourier transform spectrometer at the National Solar Observatory (Kitt Peak).

Abstract The infrared spectrum of diazirine has been recorded at Doppler resolution with a high informa­tion Fourier transform spectrometer. The ν3 fundamental has been reinvestigated and the overall assignment of the rovibrational transitions has been carried out. From the least-squares analysis a more accurate set of molecular constants including the sextic centrifugal distortion constants has been determined for the level υ3 = 1 and will be reported here. The higher resolution achieved here allowed the assignment of weaker lines and many Q branch transitions. Moreover many blended lines have now been resolved and could be properly assigned.

Vibration Rotation

Vibration–rotation spectra of HNO (DNO) have been observed in a flow system following the reaction of hydrogen (deuterium) atoms with NO. The spectra were recorded at approximately Doppler limited resolution with a large Fourier transform spectrometer. Complete analyses have been made of the ν1 bands of HNO and DNO with the following results (in cm−1).[Formula: see text]Spectra of ν2 (NO stretching) were also observed in both HNO and DNO, but ν3 (bending) proved too weak to be detected in either molecule.

The high-resolution infrared spectrum of BrCl has been observed with a Fourier transform spectrometer. About 850 spectral lines for the Δν = 1 sequences of the four isotopic species, 79Br35Cl, 81Br35Cl, 79Br37Cl, and 81Br37Cl have been measured between 417 and 461 cm−1. They have been fitted with a standard deviation of 0.000 146 cm−1 to a Dunham potential function using eight coefficients that included two Watson-type Δ correction terms. Dunham Yij coefficients have been derived for each of the four isotopic species. The equilibrium internuclear distance re of BrCl is 2.136 053 28 (67) Å.

The mid-infrared spectrum of 15N-labeled diazirine has been recorded using a Fourier transform spectrometer at a resolution of 0.08 cm-1. The v3 fundamental at 1452.49 cm-1 which essentially corresponds to a symmetric methylene deformation has been analyzed in detail. The rovibrational assignment is given and, using Watson’s A-reduced Hamiltonian, the rotational and centrifugal distortion constants for the v3 = 1 level could be determined.

And Performance

Abstract We report the design and performance of an improved version of a microwave Fourier transform spectrometer in the frequency region between 26 and 40 GHz for the investigation of rotational spectra. The performance is illustrated by rotational transitions of allene-d4 and isotopomers of carbonyl sulfide in natural abundance. The high sensitivity of the spectrometer allows the measurement of very weak lines in only a few minutes
