Quadruple bond electrons (σπδδ*) has an Os–Os triple bond and a staggered geometry. Many other compounds with quadruple bonds between transition metal atoms have been described, often by Cotton and his coworkers. Isoelectronic with the dirhenium compound is the salt K[MoCl] (potassium octachlorodimolybdate). An example of a ditungsten compound with a quadruple bond is ditungsten tetra(hpp). Quadruple bonds between atoms of main group elements are unknown. Molecular orbital theory shows that there are two sets of paired electrons in the sigma system (one bonding, one antibonding), and two sets of paired electrons in a degenerate π-bonding set of orbitals. This adds up
WFPG-TV WFPG-TV WFPG-TV was one of the earliest UHF television stations in the United States, licensed to Atlantic City, New Jersey. The station broadcast over channel 46 from December 1952 until May 1954, and held affiliations with all four major networks of the era: NBC, CBS, ABC and DuMont. Geographically, New Jersey is sandwiched between New York City and Philadelphia. Between them, the two large cities were granted most of the available VHF channels. The only VHF station assigned to New Jersey was located in Newark, the state's largest city. However, channel 13—WATV, later to become WNTA-TV (and now WNET) --
