The dependence of the fluoresrrnce spectra of some aromatic hydrocarbons and phthalocybines in solid solutions at 4.2 K on the frequency of laser excitation has been studied. It has been found that "multiplets" exist in the fluorescence spectra in the c-a-se when laser excitation occurs in the vibro

✦ Synopsis
A new method is proposed for obtaining tine structure in broad-band absorption spectra of organic molecules in solid solutions at low temperature. This method is based on the laser burning of a series of narrow gaps in inhomogeneously broadened absorption spectra. A special spectral set-up has been developed for the measurement of the differential spectrum (a "hole-burning spectrum") of "burnt" and "unburnt" samples. As an example the hole-bulning spectrum of Zn-tetraphenylporphine in ethanol has been considered.

## Abstract It is demonstrated that in a case where neither the proton nor the natural‐abundance ^13^C‐satellite spectra of a partially oriented molecule carry enough structural information, one can determine the entire molecular geometry by the combined use of several liquid crystals as solvents.
