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.
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.

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.
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).
The center part of the signal in Fig. 9(b) results from a small leak of E ‖ EStark.
The small asymmetry splitting in CH3OH occurs only for A-type states, and is significant only for small K, as discussed in Ref. 3. For asymmetry parameter κ see Ref. 15.

Two CH3OH absorption resonances were observed within the Doppler widths of two CO2 pump lines, the 9P(36) and 9R(16). See Table I.
