Abstract

Spectral Holes are extremely sensitive to external pressure changes Ap [1], They shift and broaden already at pressure changes as low as 0.1 MPa. In this paper we focus on the frequency shift s of the holes. The frequency shift can be interpreted in a simple way on the basis of two system parameters. These are the isothermal compressibility n and the solvent shift v, of the burnt molecules: The conditions under which eq. 1 holds follow from the more general Laird-Skinner model [2].
