Abstract

The a3Σg+−c3Πu,Δv=1 sequence bands of the spectra of H2 around 4μm was observed in emission by Dabrowski and Herzberg. We observed the same system in absorption through a modulated d.c. discharge in H2(∼500mTorr) with much higher resolution (Doppler limited). The fine structure due to spin-orbit and spin-spin interactions was fully resolved, and these fine structure constants were determined.
