Figure 2: Plot of calculated versus frequency. The was calculated at  K,  K, ,  cm−1, , oven temperature of 955 K, and a mass loss of 2.0 g/hr, corresponding to a probed number density of in the expansion of  cm−3. The assumed noise level was 1.0 ppm and the linewidth for the transitions was set to 0.0004 cm−1. The largest value of for a single rovibrational transition is ~130. These parameters are similar to our experimental parameters for attempt 1 listed in Table 1. The value for comes from [17].
