The thermal decomposition of 2,3-di~ethy l - J-hydr operox y- 1 - butene , p r epared f rol") singl e t oxygen, has been studied i n three solvents over the tempe r a ture r ange from 1500e to l o00e and t!1e i 111 t ial ~oncentrfttl nn r Ange from O. 01 M to 0.2 M. Analys i s of the kine tic data ind ica te s i nduced homolysis as the n ost probRble mode of d e composition, g iving rise to a 3/2 f S order dependence upon hy d.roperoxide concent :r8.tl on . Experimental activation e nergies for the decomposition were f ound to be between 29.5 kcsl./raole and 30.0 k cal./mole .• \,iith log A factors between 11 . 3 and 12.3. Product studies were conducted in R variety of solvents a s well as in the pr esence of a variety of free r adical initiators . Investigation of the kinetic ch a in length indicated a chain length of about fifty. A degenerat i ve chain branching mechanism 1s proposed which predicts the multi t ude of products which Rre observed e xperimentally as well as giving activation energies and log A factors si~il a r to those found experimentally .

The one-electron reduced local energy function, t ~ , is introduced and has the property < tL)=(~>. It is suggested that the accuracy of SL reflects the local accuracy of an approximate wavefunction. We establish that <~~>~ <~2,> and present a bound formula, E~ , which is such that where Ew is Weinstein's lower bound formula to the ground state. The nature of the bound is not guaranteed but for sufficiently accurate wavefunctions it will yield a lower bound. ,-+ 1'S I I Applications to X LW Hz. and ne are presented.

Lt. Daniel Shannon fl. 1777-1822, was the only son of Susan Drake, granddaughter of Rev. Thomas Drake, eldest brother of Sir Francis Drake, and Captain Daniel Shannon of the Royal Navy. He married Elizabeth Garvey, daughter of Alexander Garvey and Catharine Borden of New Jersey. Lt. Shannon was a Regular in the British Army and on February 12, 1777 he joined the Royal Standard, 5th New Jersey Volunteers. After being arrested and sentenced to hang for spying he was pardoned through the efforts of his mother Susan Drake Shannon who pleaded his case with the Governor. He served under General Cornwallis at the surrender in Virginia in 1781. In 1783 he moved to New Brunswick, Canada where he was reduced to a half-pay ensign in the 2nd Regiment of the Lincoln Militia. He was granted 500 acres of land on the St. Johns River, and on April 1, 1786 his daughter Catharine was born there. The family returned to the United States, residing in Pennsylvania, for a short time. In 1800 Lt. Shannon, with his mother and family, returned to Canada and settled in Stamford Township where he bought 200 acres of land on the Niagara River near the whirlpool. He later served in the Secret Service during the War of 1812 and was stationed at a lookout point on the Niagara River below the falls. In 1806 Shannon’s daughter, Catharine, married Thomas Lundy, fourth son of William Lundy of Stamford Township.
