Figure 15
Electron density distribution of BCA. Plots are shown at various pressures and from various sources: PDFT indicates periodic DFT calculations at B3LYP level of theory; XCWFN indicate X-ray constrained (restrained) wavefunction calculations at Hartree–Fock level that used experimentally measured X-ray diffraction data as constraints (restraints); MM is for electron densities derived from multipolar expansion, with coefficients refined against experimentally measured X-ray diffraction intensities. Experimental data at ambient pressure are taken from Destro & Merati (1995BB56), collected at 19 K; the 7.7 GPa data are from Casati et al. (2016BB37). Reprinted with permission from Casati et al. (2016BB37).
