Abstract
Spectra of an electrodeless discharge from a quartz tube containing Mercury and Argon show a group of bands between 2780 and 2845{\AA}. Most of these bands are shaded to longer wavelengths. These bands are well developed with an Argon pressure of about 6 mm and with the Mercury pressure equal that for room temperature. High dispersion spectra (1.2 {\AA}/mm) have been obtained in the fourth order of a grating spectrograph. An analysis of the bands give the following preliminary constants: [""FIGURE]"" $$\begin{array}{lll}\nu_{e}=35,454.1\,cm^{-1}&&\omega^{\prime}_{e}= 104.6\,cm^{-1}\quad \omega^{\prime}_{e}\ x_{e}{^{\prime}}=1.2\,cm^{-1}\\&&\omega^{\prime \prime}_{e}= 112.3\,cm^{-1}\quad \omega^{\prime \prime}_{e}\ x_{e}{^{\prime \prime}}=1.12\,cm^{-1} \end{array}$$These bands require both Hg and A for excitation. At higher Hg pressure, the bands are quenched and only spectra of mercury are observed.
