MR. T. V. BARKER has discussed in NATURE of May 12 the theory advanced by Fedorov and Shearer with reference to the relations between molecular and crystal symmetry. According to this hypothesis ...

The experimental verification of the solutes molecular symmetry requires the in-situ measurement of the solution structure in a highly supersaturated solution. However, in a conventional ...

The quantum rules shaping molecular collisions are now coming ... When they compared their results to quantum theory, they found that symmetry dictated which transitions were allowed and which ...
