Abstract
The magnetic resonance of the NO molecule is observed using the 78-, 79-, and 119-μm lines of the O laser as the radiation source. The resonances in three cases are due to the , , and transitions, respectively. Most of them are magnetic dipole transitions, but a few electric dipole transitions are also observed. It is found that the calculated factors , , , , and the calculated -doublet separations MHz, MHz, are consistent with our experimental results. The hyperfine structure and the second-order effects are also in agreement with theoretical values. The average separation between the and states for a given , which we call , is found to be 126.4469±0.0005 and 127.5786±0.0005 for , respectively. The conventional spin-orbit coupling constant is found to be 123.1580±0.0010 when . [The conventional spin-orbit coupling constant , commonly referred to as , is given by in our notation.] The coupling constant for the term is found to be -0.006±0.002 .
