 Title: TIME RESOLVED ROTATIONAL RELAXATION IN $^{13}CH_{3}F$ Creators: McCormick, Rodney I.; Skatrud, David D.; De Lucia, Frank C. Issue Date: 1985 Publisher: Ohio State University Abstract: Rotational relaxation has been studied in the excited vibrational state of optically pumped $^{13}CH_{3} F$ by means of millimeterwave spectroscopy. The excitation is provided by a Q-switched $CO_{2}$ laser whose pulse width is less than 1 $\mu \sec$. We have previously reported the results of a cw $study^{1}$ of this system in which a rate equation model was used to calculate collisional transition probabilities. The results of these studies will be compared. Description: $^{1}$W. H. Matteson and F.C. De Lucia, IEEE J. Quant. Electronics QE-19, 1284 (1983).
