✦ Synopsis

Ultraviolet absorption and dichroism measurements on oriented films of calf thymus deoxyribonucleic acid (DNA) a t varying degrees of hydration show a structural hysteresis which occurs within a relative humidity of 0 to 85% RH. This hysteresis is interpreted on the basis of a model which assumes the existence of structure-stabilizing hydrogen water bridges in the I>K-4 double helix.
