Abstract

The possibility to investigate the influence of external electric and magnetic fields on complex molecules in amorphous solids is essentially limited by a large width of their spectral bands (Δν=10²-10³ cm⁻¹ even at liquid helium temperature). Hole-burning opens up new excellent opportunities for using the Stark and Zeeman effects in spectroscopy of molecules and solids and their different applications [1]. Owing to the small hole width (Δν=10⁻¹-10⁻² cm⁻¹ at 2-5 K) the sensitivity of measurements increases by several orders of magnitude.
