Abstract

The method of Lamb dip spectroscopy in Stark tuned molecular gases is discussed and applied to the experimental assignment of methyl alcohol infrared transitions in the υ5 C−O stretch band. Theoretical expressions for Stark Lamb dip patterns are derived for P, Q and R-branch transitions. Stark tuning results and transition quantum number assignments are presented for several 10μm transitions, along with measured values of resonant frequencies, absorption coefficients and pressure broadening coefficients.

    Note that for P and R transitions with low J-values the multiplets may partially overlap, since δ is not much smaller than Δ [Eqs. (23)–(25)], making the pattern difficult to interpret.Google Scholar

    A calibration of the PZT mirror movement alone did not provide an accurate frequency scale. The actual laser frequency was somewhat offset from the cavity mode peak due to the ∼25% frequency pulling which was present in the low Q, grating coupled laser cavity.Google Scholar

    This expression can be derived from the formula for the absorption [Ed. (12)] by taking the difference between\(\alpha |_{(E_0 + e)} \) and\(\alpha |_{(E_0 - e)} \) and simplifying for Jδ≪γ.Google Scholar

    The possibility of absorption by P-branch transitions was excluded because these lines fell in the region of the υ5 CH3OH absorption where the R-branch lies (Ref. 2).Google Scholar
