摘 要
碳酸鈣、草酸鈣、磷酸鈣的成分及分子結構不同，因此在紅外線光譜圖呈現明顯的不同吸收帶。從三種純物質及混合物的紅外線光譜圖，得到碳酸鈣的特定吸收帶有三個，吸收頻率分別為1429，877及713cm-1，草酸鈣的特定吸收帶有五個，吸收頻率分別為1646（1621），1384，1318，782及518cm-1，磷酸鈣的特定吸收帶有五個，吸收頻率分別為1456，1384，1033，603及564cm-1。

Abstract
Infrared virational absorption bands of calcium carbonate, oxalate and phosphate are different significient because of the composition and structure of these compounds are different. The characteristic absorption bands of calcium carbonate are 1429, 877, 713cm-1; calcium oxalate are 1646(1621), 1384, 1318, 782, 518cm-1; and calcium phosphate are 1456, 1384, 1033, 603, 564cm-1.
