摘要: Abstract The quadrupole spectrum of molecular hydrogen has been investigated with spectroscopic instruments high resolution and a large 44-meter multiple reflection absorption cell. frequencies seven lines in the 1-0 band two 2-0 were measured. Pressure shifts obtained for five band. These data used to obtain precise constants first few vibrational states. Intensity measurements on bands S(1) line 3-0 made corrected by means an empirical curve growth. are compared theoretical calculations matrix element.
