The report briefly describes work to probe electronic properties of large molecules using low temperature spectroscopic methods and by studying the effects of external fields on high resolution spectra. The measurements of the Stark effect on the benzophenone crystal were completed. A Study of the singlet and triplet states of dichlorobenzophenone excitons in electric fields was completed. The dipole moment of the pyridine molecule in its lowest singlet n pi state was determined. A Zeeman effect study of solid carbon disulphide was completed and showed the correctness of assignments based on applications of theory to gas phase spectra.
