Crystals of calcium tartrate tetrahydrate were grown in silica gel medium in pure form and with barium, strontium, cobalt, nickel, manganese, zinc, and cadmium as dopants. The crystals, with formula D x Ca 1+x (C 4 H 4 O 6 ).4H 2 O (where D β«Ψβ¬ doping atom), were characterized by X-ray di4raction, p
Single crystals of copper formate tetrahydrate were gown at room temperature. Spectra in the near infrared at room temperature and in the visible at room and liquid air temperatures were recorded on a Unicam SF'-7C0 spectraphotometer and Hilger medium quastz spectrograph respectively. l%e observed a
