dc.description.abstractThe systematic two-photon spectroscopy study of the $\nu_{2}$ - band of $^{14}NH_{3}$ and $^{15}NH_{3}$ made by Friend and $Oka^{1}$ has been extended in two ways. Using wideband intracavity cells it has been shown that this type of spectroscopy is possible with ammonia using very low microwave powers (only 20mW) with laser lines up to 10 GHz off-resonant with infrared transitions. A total of 39 and 11 transitions were measured in the $\nu_{2}$ bands of $^{14}NH_{3}{^{2}}$ and $^{15}NH_{3}{^{3}}$ respectively with $^{13}CO_{2}$ and $C^{18}O_{2}$ lasers. Using the newly identified coincidence between the R(18) $^{13}CO_{2}$ laser line and the $Q^{5,4}$ transition of $^{15}NH_{3}$ double resonance effects were observed. Signals were also observed which were interpreted as being produced by velocity-tuned multiple-photon processes. Two-photon measurements have also been carried out in the $\nu_{1}$ band and the $\nu_{5} \rightarrow \nu_{5} + \nu_{1}$ hot band of HCCF. Our earlier double-resonance studies of $CF_{3}I^{4,5}$ using four normal $CO_{2}$ laser lines have been extended by the use of a $C^{18}O_{2}$ laser together with a fast-scan technique utilizing a wide-band intracavity cell.en_US
