Quadruple bond to give a bond order of 2, meaning that there exists a double bond between the two carbons in a dicarbon (C) molecule. The molecular orbital diagram of diatomic carbon would show that there are two pi bonds and no sigma bonds. However, a recent paper by S. Shaik et al. has suggested that a quadruple bond exists in diatomic carbon. Quadruple bond A quadruple bond is a type of chemical bond between two atoms involving eight electrons. This bond is an extension of the more familiar types double bonds and triple bonds. Stable quadruple bonds are most common among
Owned-and-operated television stations in the United States Corporation's CBS Television Stations subsidiary with the network instead of Fox's UPN-affiliated stations. In fact, two of the former Chris-Craft stations have the distinction of being owned-and-operated stations of two networks: WWOR-TV (the second in the New York City market after sister station WNYW, which has been an O&O of DuMont and Fox), and KCOP-TV (the first and only station in the Los Angeles market), both having been O&Os of UPN and MyNetworkTV. Viacom/CBS sold off several UPN owned-and-operated stations during the network's final five years. Mercury Broadcasting bought Wichita, Kansas' KSCC (channel 36, now KMTW) in 2001 (the station
