Interfacing apparatus used in optical spectroscopy to a microcomputer

Abstract

The use of computers in scientific research is becoming increasingly widespread. This is due to a number of factors, such as reproducibility of experimental conditions, ease of information storage using punched cards, magnetic disks and tapes, and advantages due to central control of apparatus. This report will detail the attempt to interface a Jobin-Yvon model THR spectrometer and a Photochemical Research Associates model 1770 photon counter to a Commodore PET ™ microcomputer. This system is to be used in optical spectroscopy. It is intended that the system
