This research, part of the Experimental Physical Chemistry                      Program, utilizes electron diffraction techniques to measure                    the structure and dynamics of liquid droplets and new low                       temperature crystal phases.  These experiments coupled with                     model calculations will elucidate the nature of condensed                       phases consisting of highly supercooled microdrops and new low                  temperature crystal phases.  The data obtained in these unique                  experiments will be used by modellers to both verify their                      theoretical constructs and to suggest new models for liquids                    and solids consisting of small numbers of molecular units.                                                                                                      The electron diffraction patterns of supercooled liquid                         microdrops and new low temperature crystal phases, formed by                    homogeneous nucleation from the vapor phase in supersonic                       flows, will be observed.  The data obtained will enhance                        knowledge of nucleation and growth of molecular clusters and                    will supply stringent new tests of current theories of                          molecular liquids.  By coupling the experimental results with                   Monte Carlo simulations, more realistic representations of the                  interactions between polyatomic molecules will be made.  In                     view of the fact that liquids are the least understood common                   form of matter, this fresh approach can be expected to yield                    new significant insights.  The other phenomenon be addressed is                 nucleation.  The ability to control the form of clusters                        nucleated and to study their structure within microseconds of                   formation will be provide useful data for the basic                             understanding of the energetics and dynamics of nucleation.
