Effects of Ring Strain for Si-O bondHammond, Paula
The mean Si-O bond length in a silicate has been found to depend, in part, on the average cation coordination of oxygen and the predicted j-character of the metal-oxygen bonds. Individual Si-O(nbr) bond lengths in four C2/m amphiboles, which apparently deviate from this correlation, are...

H atoms can break strained Si─O bonds in continuous amorphous silicon dioxide (a-SiO(2)) networks, resulting in a new defect consisting of a threefold-coordinated Si atom with an unpaired electron facing a hydroxyl group, adding to the density of dangling bond defects, such as E' centers....

athe broadening of band at 1080 cm−1 can be attributed to the increase of mean Si-O bond distance which causes by the substitution of the small silicon atom by the larger manganese atom or manganese species grafted onto the surface to form Si-Mn band by the substitution of OH group wit...
