A new technique for measuring the infrared spectra of solids has been developed. The photoacoustic spectra of hemin, hemoglobin, protoporphyrin IX, and horseradish peroxidase show how this technique can be used to obtain structural information about biological materials which cannot readily be studied by normal transmission infrared spectroscopy. The method requires milligram quantities of material and involves no sample preparation.
一种测量固体红外光谱的新技术已经被开发出来。血红素、血红蛋白、原卟啉IX和辣根过氧化物酶的光声光谱展示了该技术如何用于获取生物材料的结构信息，而这些生物材料难以通过常规透射红外光谱进行研究。该方法需要毫克级的材料，并且无需样品制备。
