ABSTRACT:

In this paper, the chemical shift Values of 11B in some "single" borate anions have been reported and the peak-phase transformation phenomenon in pentaborate solutions was firstly recorded and discussed. Furthermore, the NMR peaks were assigned to certain boron atoms or groups and the reaction mechanics of the diluting processes of two series of borate solutions have been investigated.
