dc.description.abstract E. B. Wilson and R. H. $Hughes^{1}$ invented the Stark modulation microwave spectrometer in 1947 and demonstrated the power of molecular modulation in increasing the sensitivity of spectroscopy. We report here the construction of a Stark cell for solid state spectroscopy inspired by Wilson's initial work. Unlike in gas phase microwave spectroscopy where the modulation depends on the frequency shift of spectral lines, we plan to use the intensity variation of spectral lines due to the applied electric field. Such an effect was theoretically predicted by $Condon^{2}$ and has been experimentally demonstrated in gaseous $hydrogen^{3.4}$. The field induced transitions are functions of the molecular polarizability and as such obey Raman type selection rules. We should thus observe sharp spectral lines with $\Delta k=0$. Construction of the Stark cell is in progress. We envisage that this will increase the current sensitivity of solid hydrogen spectroscopy by several orders of magnitude. en_US
