Authors: Tsunakawa Mitsuaki , Ohba Akihiro , Sasaki Nobuki , Kabuto Chizuko , Kato Tadahiro , Kitahara Yoshio , Takahashi Norindo 
Published: July 2006

The stereochemistry of C9 of previously reported momilactone-A and B (I and II) has been erroneously written and should now be revised to β -configuration with respect to hydrogen atom as in M-C.

Authors: Yamamoto Masahide , Hatano Yoshihiko , Nishijima Yasunori 
Published: July 2006

Abstract
Compounds:(Remark: Graphics omitted.) which show intramolecular exciplex emission have been synthesized, where CZ is the carbazole group and n = 1, 2,3,4, and 5. The absorption spectra and emission spectra of these compounds were studied; both normal fluorescence and intramolecular exciplex emission were strongly affected by methylene chain length. Very rapid exciplex formation (less than a few nsec) is indicated by the measurement of emission lifetime.

Authors: Atake Tooru , Suga Hiroshi , Chihara Hideaki 
Published: July 2006

Abstract
A small anomaly in heat capacity appeared at about 18 K when α-carbon monoxide was annealed at 15–16 K for 20–40 hours. A relaxation phenomenon was observed between 14 and 19 K. The results were tentatively interpreted as due to a glass transition arising from freezing of molecular head-to-tail reorientation.

Published: July 2006

Abstract
The microwave spectrum of 2-furancarbonitrile has been studied in the frequency region from 10 to 20 GHz. The rotational constants (MHz) for the ground vibrational state are determined to be A=9220.0±0.2, B=2029.27±0.01, and C=1662.64±0.01. The dipole moment is determined to be μ=4.71±0.02 D with the components μa=4.62±0.02 D and μb=0.90±0.01 D. These data suggest that the furan ring is probably distorted.
CALORIMETRIC STUDY OF THE PHASE CHANGES IN SOLID ETHANE
Authors: Atake Tooru , Chihara Hideaki 
Published: July 2006

Abstract
The heat capacity of solid and liquid ethane was measured between 50 and 100 K. The transition occurs at 89.813 K with the heat of transition 2282 Jmol−1. The triple point is 90.341 K and the heat of fusion is 583 Jmol−1. The entropy of fusion is as small as 6.46 JK−1 mol−1, indicating that the high temperature phase is a plastic crystal. The volume changes associated with the transition and fusion were derived as 1.05 cm3mol−1 and 4.1 cm3mol−1, respectively. Molecular motion in the plastic phase is discussed.

TEMPERATURE EFFECT ON THE INTERSYSTEM CROSSING OF ACRIDINE IN VARIOUS SOLVENTS
Authors: Uji-Ie Koji , Kasama Kunihiko , Kikuchi Koichi , Kokubun Hiroshi 
Published: July 2006

Abstract
lative yield of the lowest triplet state of acridine increases with increasing temperature in water, ethanol, and isopropanol, but decreases in methylmethacrylate (MMA) and polymethylmethacrylate (PMMA). In benzene it remains constant in the range of 278 to 336 K. The lowest excited singlet state is of π,π* character in all the solvents studied. The energy gap between the singlet π,π* and n,π* states is larger in the order of water&gt;alcohols&gt;MMA, PMMA and benzene. The intersystem crossing through the singlet n,π* state becomes less singnificant for larger energy gap.

The result indicates that asymmetric induction takes place before the making up of the diastereomeric alkyl-Pt intermediate.
