Definitions for "UHF"
Keywords:  ultra, mhz, ghz, megahertz, ltra
Ultra High Frequency. (1) A bonded-wafer process technology used in Melbourne, Fla. for fabrication of enhanced bipolar products, particularly linear and high-frequency operational amplifiers and other linear products. (2) Also, the portion of the radio spectrum between 300 and 3000 megahertz (MHz). This includes television channels 14 through 83, as well as most radar use.
Acronym: ltra igh requencies Communications: The frequency band between 300 MHz to 3000 MHz. Video: Broadcast channels 14 through 69 (inclusive).
ltra igh requency. Refers to frequencies between 300 and 3000 MHz. (see HF, VHF)
Spin-unrestricted Hartree-Fock. For open-shell molecules. There are separate orbitals for spin-up (alpha) and for spin-down (beta) electrons. UHF wavefunctions are usually not eigenfunctions of spin, and are often contaminated by states of higher spin multiplicity (which usually raises the energy; see PUHF).
Unrestricted HF method.
(Unrestricted Hartree-Fock) The self-consistent field method without the restriction of pairing up and down electrons. Unlike the restricted case, where the spin-orbitals are defined such that each spin up and spin down pair have the same spatial form, in the unrestricted space every spin-orbital has different spatial forms. The drawback to this approach is that the UHF wavefunction does not have to be an eigenfunction of the S^2 operator, while the RHF will always be an eigenfunction of the S^2 operator.
UHF (also known as The Vidiot from UHF in Australia and parts of Europe, and Los Telelocos in Mexico) is a comedy film made in 1989. It starred "Weird Al" Yankovic, Michael Richards, David Bowe, Victoria Jackson, Fran Drescher, Kevin McCarthy, Gedde Watanabe, Billy Barty, Anthony Geary and Trinidad Silva. The film was directed by Jay Levey, Yankovic's manager, who also co-wrote the screenplay with him.
UHF is an original song by "Weird Al" Yankovic in the key of F major. It is the theme song from the film UHF. It is a style parody of themes that are played to advertise television stations.
