This paper compares the absolute shieldings obtained by gauge‐including‐projected‐augmented‐wave (GIPAW) to those obtained by gauge‐invariant atomic orbital/Becke, 3‐parameter, Lee‐Yang‐Parr (GIAO/B3LYP)/6–311++G(d,p)‐polarizable continuum model (PCM, dimethyl sulfoxide) for nine benzazoles (benzimidazoles, indazoles,… Click to show full abstract
This paper compares the absolute shieldings obtained by gauge‐including‐projected‐augmented‐wave (GIPAW) to those obtained by gauge‐invariant atomic orbital/Becke, 3‐parameter, Lee‐Yang‐Parr (GIAO/B3LYP)/6–311++G(d,p)‐polarizable continuum model (PCM, dimethyl sulfoxide) for nine benzazoles (benzimidazoles, indazoles, and benzotriazoles) recorded in the solid‐state. Three nuclei were explored, 13C, 15N, and 19F, and the gauge‐including‐projected‐augmented‐wave approach only proved better for 15N MAS NMR.
