Abstract:

The object of this research project was to investigate new vapor phase chemiluminescent reactions between alkali atoms and halide molecules in order to discover promising candidates for short-wavelength chemical lasers. Many reactions were studied and several of these were found to produce visible emission from electronically excited molecules. Five of these reactions produced molecules that had either vibrationally inverted populations in the excited state or had transitions to high lying vibrational levels of the ground state, making them potential chemical laser candidates.
