Cold ions of tetrafluorobenzene isomers were produced by pulsed glow discharge in a supersonic free jet and the electronic spectra due to D2–D0 transitions were observed. The vibrational frequencies of the ions were determined for the ground and electronically excited states through observations of the fluorescence excitation and dispersed fluorescence spectra under collision-free conditions. The vibronic bands observed in the spectra were assigned to totally symmetric vibrations. The difference in the vibrational frequencies between the ion and neutral molecules is very small in spite of the ejection of an electron from the π orbital. A very small frequency change is observed in the electronic excited state of the ions. The frequencies observed for the ions show that the bonding π orbitals are less effective for chemical bonds of the molecules. The electronic spectra of the 1,2,4,5-tetrafluorobenzene cation, whose neutral parent molecule is distorted in the S1 state along the fluorine-wagging normal mode...

The case was 58 years old male. His chief complaints were fever and depressed consciousness. He had a history of aortic valve replacement on March 2006. On November 2010, we implanted ICD at the left subclavian space for treatment of sustained polymorphic VT. On the 15th day after operation he felt fever, and on the 17th day he became shock state with the deterioration of his consciousness, leading to the emergent admission of our hospital. His wound showed pus-discharge, so the extraction of his ICD generator and lead was performed on the second hospital day. But septic shock continued for 7 days with three types of antibiotics medication and drainage. The culture from his blood and wound showed Methycillin sensitive Staphylococcus aureus. The antibiotics change from Vancomycin to Ampicillin relieved his bacteremia and lowered fever on the 11th hospital day. On the 66th hospital day we newly implanted ICD system at the right subclavian space and on the 70th day he was discharged from our hospital.
