The fluoroacetyl chloride sample was entrained in 70:30 Ne–He carrier gas mixtures at a pressure of 2 atm and expanded into the cavity with a reservoir nozzle [10] made from a modified Series-9 General Valve. The reservoir nozzle AZ 12080282 mounted in a recessed region of the mirror flange which is external to the vacuum chamber and the expansion passes through a 0.182-inch diameter hole into the resonant cavity. The center of the expansion is offset from the center of the mirror by 1 inch.
