An intriguing feature to note is how the bond length and angle change when the tautomeric structure's σF values change19,21,21. i.e., σF is the value of change in factor of the bond length and bond angle when adding any para substituent on the benzene ring; in this case (our ...
It has long been recognized that the 29Si and 27Al NMR chemical shifts for aluminosilicate crystals and glasses correlate to some extent with the T−O−T bond angle (where T is the tetrahedral atom Si or Al). With increasing T−O−T bond angle, the 29Si and 27Al NMR shieldings...
