Laser and Fourier Transform Spectroscopy of Novel Propellant Molecules
Abstract
A wide variety of energetic molecules have been studied by the techniques of Fourier transform spectroscopy and visible laser spectroscopy. Molecules observed include trinitrogen, silicon carbide dicarbon, tricarbon, pentacarbon, Rydberg molecules, boron hydrides and deuterides, dicarbon nitrides, metal monoborohydrides. These molecules were detected by absorption or emission measurements in the infrared, visible and ultraviolet regions of the spectrum. The antisymmetric stretching vibration of sub 3 was detected in absorption near 1645 1/cm. New Fourier transform electronic emission spectra of SiC, C Sub 2 and C Sub 3 were found in the infrared. Infrared electronic emission spectra were also recorded for the Rydberg molecules He2 and XeH. Infrared vibration-rotation absorption spectra of C Sub 3 and C sub 5 were discovered in a carbon star. Visible emission spectra of BH, BD and CCN were recorded with the Kitt Peak Fourier transform interferometer. For CCN, ultra- cold emission from a free radical jet expansion source was analyzed. CaBH4 and SrBH4 were made by the reaction of Ca and Sr vapors with diborane, B2H6, and detected by laser-induced fluorescence.
