✦ Synopsis

Data are presented for oxytetracycline-, anthracene-, phenothiazine-, and salicylic acid-ad juvant systems indicating significant interactions in equilibrated samples and those prepared by compression techniques studied by diffuse reflectance spectroscopy. Spectral changes, both in the visible and ultraviolet regions, along with color changes, substantiate these interactions. Although the mechanism of these interactions is not fully understood, data presented indicate that these complexes are of the donor-acceptor variety.
