Abstract

Many authors have noted the importance of low temperature absorption spectra and have described various attachments to obtain these with commercial instruments. These attachments vary widely in expense, temperature capabilities, construction time, alignment problems, purpose, applicability to specific instruments, ease of use, and in many other ways. The present modification appears to be superior to most of the reported methods for low temperature absorption measurements between room temperature and -180°C. It requires only minor modifications of the Farrand spectrofluorometer (Mark I) with the cryogenic accessories. A modification of this design could be used in other spectrometers.
