✦ Synopsis

An external modulated cw narrow band laser and a collimated molecular beam was used to apply high-resolution quantum beat spectroscopy to the molecular eigenstate spectrum of pyrazine. A resolution of 1 MHz was achieved in the near ultraviolet region. A beat pattern was observed from the temporal decay following excitation of a molecular eigenstate in the .I' = 1, K' =O manifold. From the inhomogeneity of the molecular eigenstate spectrum it is concluded that it is difficult to deconvolute the molecular eigenstates into unperturbed zero-order states of pyrazine.
