$^2^9Si$ and $^3^1P$ NMR spectra have been studied in a series of lead phosphosilicate glasses, It is found that as the $P_2O5$ content increases, the signal due to the six-coordinated silicon at - 212 ppm grows in intensity. Based on partial charge arguments it is suggested that the six-coordinated silicon atoms are surrounded by only phosphorus as second neighbours and are highly desheilded.
