Among the four most widely implemented corrections (vide supra) and their modified (M) counterparts, shifts with (BJ) damping have consistently smaller means, MASs, and standard deviations than those with (0) damping; however, the (BJ) varieties exhibit broader ranges than their (0) counterparts. Notably, the minimum and maximum observed shifts both involved ω5(H-C-N bend). With ωB97X-D, ω5 decreased by a striking 56.7 cm -1 , whereas the DSD-PBEB95-D3BJ increased ω5 by 62 cm -1 . Presumably, these large shifts are a direct consequence of the extremely flat H-C-N bending potential of fulminic acid.
