Accuracy in bond lengths

The crystal structure of phenanthrene has been solved by Basak (1950), and his (two-dimensional) data refined by Mason (1961) using least-squares methods. The accuracy of this analysis is not high because of the limited number of data used the standard deviation in bond length is 0-05 A. The results of a three-dimensional analysis at 95°K, which is reported to be in progress (Mason, 1961), are awaited with interest. [Pg.250]

The accuracy of AMI and PM3 then, is quite good for bond lengths and angles, but fairly approximate for dihedrals. The largest error (Table 6.1) in bond lengths is 0.065 A (AMI for MeSH) and in bond angles 7.1° (AMI for HOF). The largest... [Pg.414]

This kind of microwave spectroscopy is the best technique available for determining the structure of small molecules in the gas phase. Microwave frequencies can be measured with extremely high accuracy, permitting bond length measurements literally... [Pg.181]
