Reviews three organic chemistry computer programs for TRS-80 and Apple microcomputers. Programs include "Introduction to Organic Chemistry,""Qualitative Organic Analysis," and a game called "Chemrain." Indicates that all three produce a readable screen, require exact responses, use graphics in an appealingly and…

Describes a computer program (FORTRAN and APPLESOFT) demonstrating the effect of copolymer composition as a function of conversion, providing theoretical background and examples of types of information gained from computer calculations. Suggests that the program enhances undergraduate students' understanding of basic copolymerization theory.…

Reviews three computer software packages for Apple II computers. Includes "Simulation of Hemoglobin Function,""Solution Equilibrium Problems," and "Thin-Layer Chromatography." Contains ratings of ease of use, subject matter content, pedagogic value, and student reaction according to two separate reviewers for each…

Describes: (1) an interactive computer simulation for a science fair display of chromatography inks; (2) analytical chemistry programs; (3) microcomputer-assisted drills in organic synthesis; (4) programs for conformation analysis of ethane and butane; (5) MOLPIX--a program for generating and displaying molecular structures; and (6) chemical…

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

Describes two computer programs used to aid in data analysis: (1) Develops a method for the propagation of error involving the direct calculation of the error in the dependent variable using a spreadsheet; (2) Examines a simple numerical method for solving complex equilibria. Lists a FORTRAN 77 program. (MVL)

Examines two computer interfaced lab experiments: 1) discusses the automation of a Perkin Elmer 337 infrared spectrophotometer noting the mechanical and electronic changes needed; 2) uses the Gouy method and Lotus Measure software to automate magnetic susceptibility determinations. Methodology is described. (MVL)

The ability of a microcomputer to execute several programs at the same time is called "multitasking." The nature and use of one multitasking operating system Concurrent PC-DOS from Digital Research (the developers of the CP/M operating system) are discussed. (JN)

Contains ratings of two software packages for Apple II computers: "Acid-Base Titrations, CHM311A" and "Chemical Principles for the Introductory Laboratory, CHM 384A." Both are aimed at high school and college chemistry and are rated on ease of use, subject matter content, pedagogic value, and student reaction. (CW)

Notes two uses of computer spreadsheets in the chemistry classroom. Discusses the general use of the spreadsheet to easily provide changing parameters of equations and then replotting the results on the screen. Presents a molecular orbital spreadsheet calculation of the LCAO-MO approach. Supplies representative printouts and graphs. (MVL)

The declining cost of hardware and the growing availability of supporting accessories (peripherals) have contributed to growth in the use of computers in chemistry. Examples of such uses are provided. (JN)

Describes nature and installation of the QUADLINK board which allows Apple software to be run on IBM PC microcomputers. Although programs tested ran without problems, users should test their own programs since there are some copy protection schemes that can baffle the board. (JN)

Reports the design for a principles-before-details presentation of electronics for an instrumental analysis class. Uses computers for data collection and simulations. Requires one semester with two 2.5-hour periods and two lectures per week. Includes lab and lecture syllabi. (MVL)

Provides instructions for "seeding" the random number generator (RND) in Apple computer programs. If RND is not seeded, students would see the same examples, questions, graphics features, or other information each time they turn on the microcomputer and run a program. (JN)

Discusses using an Apple II microcomputer as a Laboratory Data System (LDS) for the analysis of data fed from a UV-Visible Spectrophotometer. (SK)
