5-Methylfurfural is an organic compound with the formula C 6 H 6 O 2. An aldehyde that is derived through various extractions and reductions from cellulose products, [5] [6] it has applications as a synthetic intermediate [7] relevant to the fields of medicine, agriculture and cosmetics. [8] It is a food additive, and has FEMA number 270s and ...
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify ...
5-Methylfurfuryl alcohol is an organic compound with the formula C 6 H 8 O 2. It is one of many volatile compounds present in Nicotiana tabacum , [ 3 ] and is formed from the reduction of 5-methylfurfural , [ 4 ] a compound formed from the reduction of 5-bromo- or 5-chloromethylfurfural . [ 5 ]
Furfural is an organic compound with the formula C 4 H 3 OCHO. It is a colorless liquid, although commercial samples are often brown. It has an aldehyde group attached to the 2-position of furan.
Methoxymethylfurfural (MMF or 5-methoxymethylfuran-2-carbaldehyde) is an organic compound derived from dehydration of sugars and subsequent etherification with methanol. [1] This colorless liquid is soluble in a wide range of solvents including lower alcohols.
By applying intense tunable IR lasers, like IR-OPOs or IR free electron lasers, the wavelength dependence of the IRMPD yield can be studied. [5] [6] This infrared photodissociation spectroscopy allows for the measurement of vibrational spectra of (unstable) species that can only be prepared in the gas phase. Such species include molecular ions ...
The particle size should be smaller than the wavelength of the incident light in order to minimize Mie scattering, so this would infer that it should be less than 5 μm for mid-infrared spectroscopy. The spectra are plotted in units of log inverse reflectance (log 1/R) versus wavenumber.
