IJMS, Vol. 14, Pages 18881-18898: Spectroscopic Studies of Model Photo-Receptors: Validation of a Nanosecond Time-Resolved Micro-Spectrophotometer Design Using Photoactive Yellow Protein and α-Phycoerythrocyanin

13-09-2013 | Purwar, Namrta ; Tenboer, Jason ; Tripathi, Shailesh ; Schmidt, Marius, International Journal of Molecular Sciences, 2013

Time-resolved spectroscopic experiments have been performed with protein in solution and in crystalline form using a newly designed microspectrophotometer. The time-resolution of these experiments can be as good as two nanoseconds (ns), which is the minimal response time of the image intensifier ...

Effect of the Substitution Pattern on the Intramolecular Charge‐Transfer Emissions in Organoboron‐Based Biphenyls, Diphenylacetylenes, and Stilbenes

10-09-2013 | Yi‐Qiao Yan, Yan‐Bang Li, Jian‐Wu Wang, Cui‐Hua Zhao, Chemistry - An Asian Journal, 2013

Abstract Three series of organoboron‐based molecules, including biphenyls 1 a–c, diphenylacetylenes 2 a–c, and stilbenes 3 a–c, in which the electron‐accepting boryl and the electron‐donating amino groups are introduced at different positions, have been comprehensively investigated to explore ...

Hydration Behavior of Poly(ethylene oxide)s in Aqueous Solution As Studied by Near-Infrared Spectroscopic Techniques

09-09-2013 | Naoya Sagawa; Toshiyuki Shikata, Journal of Physical Chemistry B, 2013

Near-infrared (NIR) absorption measurements over a wavenumber range from 4000 to 12000 cm–1 were used to investigate hydration behavior of poly(ethylene oxide)s bearing molar masses of 3 × 103 (PEO3) and 20 × 103 (PEO20) in aqueous solution at a dilute regime. NIR absorption spectra for solutions ...
