Mesoscale dynamics and the microscopic origin of the Q0-mode in molecular liquids: A molecular dynamics study of tetrahydrofuran.
We investigate the microscopic origin of collective dynamics in molecular liquids at intermediate (mesoscale) length scales using large-scale molecular dynamics simulations of tetrahydrofuran (THF). In agreement with previous neutron scattering results, in this regime, the dynamic structure factor S(Q, t) of THF exhibi...
