The Fourier Transform

The infrared emission spectrum of carbon monosulfide was observed as a sequence of vibration–rotation bands in the X1Σ+ state, with strong heads of the Δν = 2 sequence degraded to the red. Eight bands of 12C32S were identified, and bands corresponding to the isotope 12C34S were also observed. The most prominent band head, that of the (2–0) band, is at 2585 cm−1, with the other heads spaced approximately 26 cm−1 to smaller wavenumbers. Our data, taken with the Fourier transform spectrometer at the National Solar Observatory (Kitt Peak) include the first reported laboratory observations of the band heads and as many as 200 lines in each band. These observations allowed the calculation of vibrational and rotational constants to higher order than previously reported.

The gaseous MgD2 molecule has been synthesized for the first time in an electrical discharge inside a high-temperature furnace. The high-resolution infrared emission spectrum of MgD2 was recorded with a Fourier transform spectrometer, and the antisymmetric stretching mode (v3) was detected near 1176.5 cm–1. The v3 band was rotationally analyzed, and the r0 Mg—D bond distance was determined to be 1.700 874(8) Å.Key words: gaseous MgD2, vibration-rotation emission spectrum, Mg-D bond distance.

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.

ABSTRACTIn this paper we report the first observations by cathodoluminescence in TEM of radiative infrared emission from dislocations in silicon. These results were obtained at 23-25K in a Philips EM400 electron microscope. Our results are interpreted in the light of earlier photoluminescence work, and the prospects for obtaining spectra from a small number of well characterized dislocations with high spatial resolution are reviewed. Preliminary results are also reported showing the infrared band-gap emission spectrum of GaInAs at 90K recorded using a small Fourier Transform Spectrometer fitted to the same electron microscope. Finally, we describe timing coincidence experiments from samples in which only those visible CL photons are counted which arrive at the detector at the same time as the corresponding transmitted electron energy loss event. We describe the use of this technique for life-time mapping in semiconductors.
