He investigated the structure of substances of high molecular weight and their formation by polymerization.
Relaxation phenomena have important implications in nuclear magnetic resonance (NMR) spectrometry, an analytical technique used by chemists to identify and probe the molecular structure of substances.
Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes.
Infrared spectroscopy can be used to identify the structure of substances such as paint or fibres and allows forensic technicians to match trace evidence from a crime scene or body to that found on a suspect or vehicle.
In the US, drugs are automatically banned if they are "substantially similar" to the chemical structure of substances that are already illegal.
In his last work, his attempt to present an argument for his ontological idealism is based mainly on (1) mereological considerations concerning the structure of substances which aim to show that only spirits can claim the status of a substance, and on (2) his theory of time, the unreality of which he famously had proven in his magnum opus The Nature of Existence (1921/27).
Raman spectroscopy, which is based on vibrational spectroscopic techniques, is used to derive the chemical structure of substances [ 3].
Measurement of impedance is easy and useful for evaluation of conductive substances based on their electrical characteristics (Ohmine et al. 2004), and it is frequently used for evaluation of the physical properties and structure of substances in industry.
IR and Raman spectroscopy provide details regarding the chemical composition and molecular structure of substances in cells and biological tissues, and they are considered to be vibrational spectroscopic techniques.
In our earlier studies, we compared the steric conformational structures of substance P[6 11] with our substance P antagonists in silico, and used the diverse biological effects of these compounds as tools in our modeling and design studies for discovering antiproliferative drugs.
