In UV-Vis spectroscopy, the value log (I0/I) where I0 is the intensity of the reference beam and I is the intensity of the sample beam.
Naturally occurring amines isolated from plants.
The conjugate base of a terminal alkyne.
Organic bases that have the functional group —NR2, where R may be H, an alkyl group, or an aromatic group. (24.4)
An addition reaction in which two groups are installed on opposite sides of a p bond.
Having the same energy.
dissolving metal reduction
A reaction in which an alkyne is converted into a trans alkene.
A reaction in which the enthalpy of the products is higher than the enthalpy of the reactants; a reaction in which heat is absorbed
An alloy in which the components are not distributed uniformly; instead, two or more distinct phases with characteristic compositions are present. (Section 12.3)
Infrared (IR) spectroscopy
A spectroscopic technique in which a compound is irradiated with infrared radiation, absorption of which causes covalent bonds to change from a lower vibration state to a higher one. Infrared spectroscopy is particularly valuable for determining the kinds of functional groups present in a molecule.
A property that is independent of the amount of material considered, for example, density. (Section 1.3)
An ion or molecule that coordinates to a metal atom or to a metal ion to form a complex. (Section 23.2)
The difference between the mass of a nucleus and the total masses of the individual nucleons that it contains. (Section 21.6)
The product of the mass, m, and velocity, v, of an object. (Section 6.4)
The study of carbon-containing compounds, typically containing carbon–carbon bonds. (Section 2.9; Chapter 24:Introduction)
A polyatomic anion that contains one or more oxygen atoms. (Section 2.8)
Biological damage caused by photosensitizers, light, and oxygen, used to kill tumor and other cells.
S (Section 3.3
From the Latin, sinister, left; used in the R,S convention to show that the order of priority of groups on a chiral center is counterclockwise
A name that is assigned using the rules of IUPAC nomenclature.
Vibrational infrared region
A common type of spin-spin coupling involving the H atoms on two C atoms that are bonded to each other.
