The RKR method for determining accurate potential energy curves is described. Advantages of using the method (compared to Morse procedure) and a TRS-80 computer program which calculates the classical turning points by an RKR method are also described. The computer program is available from the author upon request. (Author/JN)

Describes advanced undergraduate laboratory exercise examining the dependence of the rate constants and the instantaneous concentrations with the nature and energy content in a gas-phase complex reaction. Computer program (with instructions and computation flow charts) used with the exercise is available from the author. (Author/JN)

The ratings of 43 third-year medical students were used to investigate a method of computing the reliability of ratings. The students were evaluated on a four-point rating scale along seven dimensions of clinical ability: diagnostic ability; motivation; sense of responsibility; oral-verbal ability; effectiveness with patients; ability to take a…
