Title Millisecond time resolution neutron reflection from a nematic liquid crystal
Abstract The director reorientation of the liquid crystal 4,4' octyl cyanobiphenyl in the nematic phase under application of bursts of ac field have been observed using ime-resolved neutron scattering in reflection geometry. The relaxation of the irector has been shown to agree with existing theory, as determined by material and cell parameters. This result shows that it is possible to use neutron reflection measurements from buried interfaces to follow kinetic processes on a time scale comparable with the pulse length of the ISIS neutron source s20 msd.
