“…The susceptibility of the phosphine-water clusters to the population method was also investigated, and it is important to mention that this susceptibility has been reported to be a crucial factor for several systems [77][78][79][80][81][82]. Therefore, closer inspection of the variation in the phosphorous charge (qP) revealed interesting results when we considered the different methodologies (see Tables S2 and S3 O-H interaction between PH 3 and the PH 3 (H 2 O) n complexes, a decrease in qP for the phosphine-water clusters is expected.…”
