Abstract
IR absorption spectra of urea, urine without any deviation in composition and kidney oxalate calculi are studied. The shifting of stretching vibrations of carbonyl group C=O confirms that assert that the joining of calcium oxalate molecules and oxalate complexes join to urea molecules via oxygen atom of urea. The shifting of COO− symmetric stretching vibration frequencies may testify the presence of molecules and aggregates of calcium oxalates. Obtained results may be useful in developing new methods in early diagnostics of different diseases.
