Description
We report results of precise laboratory spectroscopy for a set of
astropysically important species carried out at the Institute of Applied
Physics of the RAS over the last years. The investigations are based on
Lamb-dip measurements at mm$-$sub-mm wavelengths with the developed sub-Doppler
spectrometer. In particular, from a comparison of precise radio astronomical
and laboratory frequencies of CH$_3$OH lines we estimate the
upper limit on the possible $m_e/m_p$ variation in dark interstellar clouds
as $\le1.5\times10^{-8}$.
