1. IR-spectroscopy

IR-spectroscopy는 적외선을 사용하는 분광법으로, absorption spectroscopy에 해당한다. 분광시료에 적외선을 쬐었을 때, 분자 진동과 흡수하는 에너지를 통해 작용기와 구조를 분석하는 방법이다. 광원에서 나온 빛이 시료를 통과할 때 투과된 빛의 양을 통하여 물질을 분석하는 방법이기에 mass spectrometry와 달리 비파괴적이다. 분자는 신축 운동과 굽힘 운동이라는 두 가지 방식으로 적외선 에너지를 흡수한다. 흡수되는 파수와 세기는 결합 차수, 결합을 구성하는 원소, 작용기의 종류에 따라 다르다.
2. NMR

원자 핵의 양성자는 외부 자기장과 같은 방향으로 정렬되었을 때 에너지가 낮은 a spin을 가지며, 외부 자기장과 반대 방향으로 정렬되었을 때 에너지가 높은 β spin을 가진다. 서로 다른 두 스핀 사이에는 에너지 차이가 존재하며, 해당 에너지 차이만큼의 진동수를 가진 광자를 쪼여줄 경우, spin inversion이 발생한다.

1. IR-spectroscopy

IR-spectroscopy is a powerful analytical technique that provides valuable information about the molecular structure and functional groups present in a sample. It is widely used in various fields, including chemistry, materials science, and biology, to identify and characterize organic and inorganic compounds. The technique relies on the absorption of infrared radiation by molecules, which causes them to vibrate at specific frequencies. By analyzing the absorption spectrum, researchers can identify the presence and nature of different functional groups, such as carbonyl, hydroxyl, and amine groups, as well as the overall molecular structure. IR-spectroscopy is a non-destructive, relatively simple, and cost-effective method that can be applied to a wide range of samples, from solids and liquids to gases. It is an essential tool in the characterization and identification of unknown compounds, as well as in the monitoring of chemical reactions and the quality control of various products. The continuous development of IR-spectroscopy instrumentation and data analysis techniques has further expanded its applications and made it an indispensable analytical technique in modern scientific research and industry.
2. NMR

Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique that has revolutionized the field of chemistry and materials science. NMR relies on the magnetic properties of certain atomic nuclei, such as hydrogen (1H) and carbon (13C), to provide detailed information about the structure, dynamics, and interactions of molecules. By exposing a sample to a strong magnetic field and applying radio frequency (RF) pulses, NMR spectroscopy can detect the unique resonance frequencies of different nuclei within the sample, which are influenced by their chemical environment. This information can be used to elucidate the molecular structure, identify functional groups, and study the interactions between molecules. NMR spectroscopy is particularly valuable in the characterization of organic compounds, polymers, and biomolecules, as it can provide non-destructive, high-resolution information about the three-dimensional structure and dynamics of these complex systems. The continuous advancements in NMR instrumentation, such as the development of high-field magnets and sophisticated pulse sequences, have further expanded the capabilities of this technique, allowing for the study of increasingly complex systems and the investigation of a wide range of chemical and biological processes. NMR spectroscopy has become an indispensable tool in modern scientific research, with applications spanning fields as diverse as organic chemistry, materials science, and structural biology.
