A Reinvestigation of Hexamethylenetetramine by Electron Diffraction

Abstract

Our expectation that hexamethylenetetramine should yield excellent photographs with rings extending to large angles of scattering was fulfilled, and an unusually precise interpretation was achieved. The new data include observations on fourteen maxima and shelves (s_(max.) = 32.3), one of which, A in Fig. 1, was not noticed by the earlier workers even though it appears on the part of the pattern which they observed on their photographs. The measurements agree well with the theoretical curve for our final model, showing an average deviation of only 0.008 both for the particular features considered by Hampson and Stosick and for all the features observed by us excepting the first minimum. However, the size determination exactly checks that of Hampson and Stosick, whose photographs were made in a different apparatus (at Oxford), and the angle determination precisely confirms their assumed value.
