AUTOMATIC ELECTRONIC RECORDING INTERFEROMETER. III. OPERATING MANUAL AND SOME APPLICATIONS
Abstract
Attempts to develop interferometer applications led to the re-design of the photomultiplier circuit (stabilization), the amplifier (negative feedback), the zero-adjusting and dark current cancellation circuit, and the rotation measuring bridge (now both axtuated from the main power block). A monitoring meter to check the balance of the servo-motor loop by a resonance method was added. The optical system incorporates new improvements (cooled lamp house, automatic scanning of the monochromator, interferometer slit adjustable transversally, longer decollimator tube, and improved liquid cell allowing continuous circulation of both unknown and reference fluids with an optical path increased to 5 mm). A complete modus operandi and trouble-shooting instructions are offered. Finally some applications were explored in a preliminary manner and the results are tabulated (dispersion within an absorption band, comparative dispersion of some hydrocarbon derivatives, non-aqueous titrations, dynamics of proteins denaturation and stability in solution, etc...).
