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].
