Abstract

A means is derived for calculating the number of significant figures in the slope and intercept of an experimental linear graph. The method is based on the actual scatter in the points rather than on the nominal precision in the original data, and it can be used even by students who are mathematically fairly unsophisticated.

  Abstract:
  An electron-counting scheme is presented for metal nitrosyls, based generally on the eighteen-electron rule. Square-pyramidal 4d- and 5d-transition metal nitrosyls obey a sixteen-electron rule. The stereochemistry of the coordinated NO may thus be ...
