Fig. 7. Change in each Bqk from the equilibrium values for [Yb(trensal)] as a function of mass- and frequency-weighted dimensionless displacement Qqj along a vibrational mode.42 Note that this mode is a totally-symmetric vibrational mode so that the C3 symmetry of [Yb(trensal)] is not broken and hence only certain Bqk are affected; hence, some are overlapping with zero magnitude.
