Abstract
Stark effect of the 2$\nu_{3}$ band of methane was studied by saturation spectroscopy using an optical cavity absorption cell and a 1.6-$\mu$m external cavity semiconductor laser. The magnitude of the determined dipole moments was dependent on the Coriolis sublevels. This dependence agreed with the higher-order dipole moment $^{a}$, $$\mu_{a}\infty \ell_{\beta} J_{\alpha}+J\alpha\epsilon_{r}$$ where $\mu$ is the dipole moment, $J$ are the vibrational angular momenta, $J$ are the total angular momenta, and ($\alpha, \beta, \gamma$) is ($x, y, z$) , ($y, z, x$) or ($z, x, y$) components of the molecule-fixed axes.
