It has been ascertained that thiocyanate complexes of molybdenum react with dyes of the xanthene series, Rhodamine 6G and Rhodamine B, to form ion pairs. The Mo:SCN:Rhod. component ratios are respectively 1:5:2 and 1:6:3. The ion pairs are stable in an acid medium: 4.5-5.5 M H/sub 2/SO/sub 4/ (MTC-Rhod. 6G) and 3 M H/sub 2/SO (MTC-Rhod. B), and their molecular extinction coefficients are 2.22 x 10/sup 5/ and 3.8 x 10/sub 5/ respectively; MTC in a molybdenum thiocyanate complex. A procedure has been worked out for determining molybdenum in films, making use of the reaction of forming an MTC-Rhod. B ion pair.
