Laser Magnetic Resonance

Within the last few years, laser magnetic resonance (LMR) has emerged as a powerful technique for the study of pure rotational spectra of transient species in the gas phase. The sensitivity of this method is considerably higher than that of competing techniques, such as conventional optical and microwave spectroscopy and gas-phase EPR, while the resolution attainable is comparable with that of the latter two methods. Its domain of applicability presently includes atoms, ground states of molecules with up to 5 atoms, and most recently, metastable molecular electronic states in the millisecond lifetime range, and molecular ions. The only rigorous constraint on this applicability is that the species of interest must be paramagnetic.

Good Agreement

Ten rotation–vibration transitions of the ν2 (bending) fundamental band of 13CH2 have been observed using the technique of CO2 laser magnetic resonance in the 880 to 945 cm−1 region. 13C substituted methylene was produced in a flow system by reacting 13CH4 or 13CH2CO with F atoms from a microwave discharge in CF4. Analysis of the spectra yields a number of molecular parameters for 13CH2. Specifically, the 13C isotope shift of ν2 is −3.93 cm−1 and the 13C Fermi contact hyperfine parameter is 238 ± 6 MHz for the ground vibrational state. The hyperfine parameters determined here for gas phase 13CH2 are in fairly good agreement with those determined for matrix isolated 13CD2 in earlier ESR experiments.
