Protonated methane, a.k.a. CH5+, is a highly unusual molecule that scientists and astronomers suspect may be found within the interstellar medium where stars and planets are formed. To identify ...

Microwave spectroscopy, interfaced with quantum chemical calculations, has emerged as a pivotal technique for elucidating the detailed structural and dynamical properties of molecules. This ...

THE absorption spectra of polyatomic molecules are usually so complicated that an analysis of their rotational fine structure seems impossible. We have therefore tried if the magnetic rotation spectra ...

Publications of the Astronomical Society of the Pacific, Vol. 108, No. 729 (1996 November), pp. 962-966 (5 pages) CCD spectra were obtained for the late-B and early-A type Algol binaries AI Draconis ...

Raman spectroscopy is a type of molecular spectroscopy that involves the dispersion of electromagnetic radiation by molecules or atoms. It measures the rotational, vibrational, and other low-frequency ...

Infrared spectroscopy is a standard technique, which depends upon the interaction between infrared radiation and the vibrating dipole moments of molecules. Except for homonuclear diatomics and noble ...
