摘要: The fundamental rotation–vibration band of H2 induced by an electric field has been measured at high resolution using interferometer with a limit 0.006 cm−1. frequencies and the widths absorption features have in density range 1 to 25 amagat, zero-density obtained extrapolation. lines exhibit collision narrowing, minimum width, 0.01 cm−1, occurring about 2 amagat. A new value, 1.2 cm3, for matrix element polarizability.
