Abstract
We describe a novel experimental apparatus to measure the collision broadening of rotational lines in the millimeter-wave region. The sample cell is a small acoustic detector featuring high sensitivity at low pressure. We measured the broadening coefficients for CH3CN and CH813Br and we compared them with the theoretically estimated linewidthsKeywords
