โฆ Synopsis
The molecular eigenstate spectrum belonging to the P and R branches of the 1 B3 u (0-0) electronic transition of pyrazine-h 4 was recorded with a 200 kHz wide laser in a supersonic nozzle at a temperature of ~-1 K. The square of the Fourier transform of the amplitude spectrum yields the quantum beats in the fluorescence decay that have been reported before.
