1. succinic acid

succinic acid(C4H6O4)의 IR spectrum 분석 결과, wavenumbers(cm-1)에서 1693.44의 carbonyl compound C=O, 1201.85와 1176.86의 C-OH stretch, 2932.25의 C-H, 2648.54의 O-H 결합을 가지고 있는 것으로 나타났다. 이를 통해 분자식이 C4H6O4인 화합물의 구조를 예측해볼 수 있었다.
2. salicylic acid

salicylic acid(C7H6O3)의 IR spectrum 분석 결과, wavenumbers(cm-1)에서 1659.11-1660-2000의 Aromatic ring, 1156.35의 C-O, 3414.83의 O-H, 3013.63의 =C-H 결합을 가지고 있는 것으로 나타났다. 이를 통해 벤젠고리에 C가 7개 붙은 구조의 화합물일 것이라 유추할 수 있었다.
3. HCl

HCl 기체 IR spectrum 분석 결과, p branch와 r branch로 구분되었고 이를 통해 anharmonicity constant, vibration rotation interaction constant, centrifugal distortion constant 등을 계산할 수 있었다. 선형분자이며 쌍극자모멘트가 0이 아닌 HCl이 회전과 진동을 하면서 분자 길이의 변화가 생겼기 때문에 스펙트럼의 모습에 차이가 있었다.
