Dimensional protein crystals imaged at low temperature and under low dose conditions reveal information to better than 3A resolution. Imaging under similar conditions and image reconstruction of non periodic specimens such as spherical viruses have yielded structural detail to only 30A resolution.

✦ Synopsis
High resolution transmission electron microscopy (HRTEM) studies of Bis-(2hydroxyethyl) terephthalate (BHET) crystals, prepared by a novel method which allows one to obtain large crystallites (of the order of several centimeters) are reported. The details of the crystallography, including polymorphism, as determined by X-ray diffractometry and infrared spectroscopy and their relation to the micrographs and electron diffraction results are discussed.
