| Abstract: | Two Δk = ±3 “forbidden” vibration-rotation transitions in the ν2-band of NH3 have been measured by using infrared-microwave two-photon spectroscopy and laser Stark spectroscopy. Combining these results with Rao's recent measurement of the band, we have obtained the C0 rotational constant of 6.2280 ± 0.0008 cm?1. |
