## Abstract

Stepwise multiple regression analyses of the apparent R(SiO) bond lengths were completed for coesite and for the silica polymorphs together with the clathrasils as a function of the variables f_{s}(O), P(pressure), f_{s}(Si), B(O), and B(Si). The analysis of 94 bond-length data recorded for coesite indicates that all five of these variables make a significant contribution to the regression sum of squares with an R^{2} value of 0.84. A similar analysis of 245 R(SiO) data recorded for silica polymorphs and clathrasils indicate that only three of the variables (B(O), f_{s}(O), and P) make a significant contribution to the regression with an R^{2} value of 0.90. -from Authors
