Describes interactive, computer-graphics program emulating behavior of high resolution, ultraviolet-visible analog recording spectrophotometer. Graphics terminal behaves as recording absorption spectrophotometer. Objective of the emulation is study of optimization of the instrument to yield accurate absorption spectra, including…

A PASCAL graphics and instrument interface program for a Z80/S-100 based microcomputer was developed. The computer interfaces to a stopped-flow spectrophotometer replacing a storage oscilloscope and polaroid camera. Applications of this system are discussed, indicating that graphics and analog-to-digital boards have transformed the computer into…

Describes a computer program which generates formalized PMR spectra for video display. The program includes eight problems and is written in BASIC. (SK)

Thirteen computer/calculator programs (available from authors) are described. These include: representation of molecules as 3-D models; animated 3-D graphical display of line drawings of molecules; principles of Fourier-transform nuclear magnetic resonance; tutorial program for pH calculation; balancing chemical reactions using a hand-held…
