The characteristic vibration peaks for stretching N = O also appear at 1649, 1646, and 1640 cm-1 respectively in black powder samples 60, 70, and 80 ºC which were previously shifted at wave number 1634 cm- 1 in the forming material (Lanthanum Nitrate Hexahydrate).	cache/biomedich-157.pdf	txt/biomedich-157.txt
