✦ Synopsis

Magic

-anglespinnmg NMR has been used to study Si-0-Si bond-angle distributions associated with various structural elements, Qn, present in lithium silicate glasses of different compontions. Jt is shown that glasses contain a plurahty of structural elements with a broad dlstnbution of Si-0-Si bond angles. and that the width of the distribution IS characteristic of a particular Q,, species
