The spectrum of the BH3 ν2 band was observed in the 900–1300 cm−1 region with a Fourier transform infrared spectrometer. The borane molecule was produced with a discharge in a B2H6 and He mixture. The observed spectrum was analyzed by including the Coriolis interaction from the ν4 state to determine the molecular constants in the ν2 and ν4 states. The band origins and the Coriolis interaction constant were determined to be ν2 = 1147.4986 (12), ν4 = 1196.66 (12), and D24 = 7.8034 (48) cm−1, with one standard deviation in parentheses. The previous Q-branch assignment of the diode laser spectrum was partly revised.

First Time

The spectrum of the ν3 band CH3 was observed in the 2800–3100 cm–1 region with a Fourier transform infrared spectrometer. The 76 observed lines were analyzed together with the previous difference frequency data to determine the molecular constants including sextic centrifugal distortion constants and the A1 – A2 splitting constant in the ground state. The ν4 band (out-of-plane vibrational mode) of CH2D was observed in the 550–700 cm–1 region by a discharge in a mixture of CH2DI and Ar. The molecular constants in both the ground and the ν4 states of this radical have been determined for the first time. PACS No.: 33.20Ea

Sulfate Species

The reproducibility of the KBr pelleting technique for inorganic sulfates was assessed using a Fourier transform infrared spectrometer. Day-to-day variation in peak frequencies of selected bands had standard deviations ranging from 0. to 1.5 cm−1. This 1 cm−1 standard deviation was shown to be due to changes in bandshape, probably due to variations in sample preparation from operator to operator. It was concluded that the reproducibility of sulfates in KBr is sufficient to allow the design of computerized spectral matching programs to identify specific sulfate species based on band frequencies and intensities.

Effects Of Aging

The application of the newly developed technique of photoacoustic infrared spectroscopy, using a Fourier transform infrared spectrometer, to the measurement of the infrared spectra of single slabs of various coal types is described. The effects of aging of coal surfaces, which include both oxidation and abrasion, are clearly apparent in a comparison of the spectra of freshly cleaved and aged coal surfaces.
