Vibrational Modes of Methylene Chloride - Purdue University
WebSep 5, 2024 · Infrared spectroscopy is based on molecular vibrations caused by the oscillation of molecular dipoles. Bonds have characteristic vibrations depending on the atoms in the bond, the number of bonds and … Dichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula CH2Cl2. This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents. http://jabjorklund.faculty.noctrl.edu/Organic/Organic%202/221labs/6_friedel_crafts.pdf cost cutters muscatine iowa
