The multiplex BOXCARS configuration allows accurate determination of rotational constants and rotational temperatures, and offers a great number of advantages over other methods. The technique was applied to calibrate the cooling effect of a pulsed molecular beam of N2 and to study the rotational energy distributions of infrared multiphoton excited C2H4.}, url = {/files/mazur/files/rep_71.pdf}, author = {K.
