A variety of fluorescent molecular viscosity probes have been widely used for mapping the local viscosity in cells and for monitoring the microenvironments in materials. However, their viscosity-sensing structural design still relies strongly on mole

Picosecond time-resolved Raman spectra of β-carotene in the excited S 2 ( 1 B u + ) state have been obtained in resonance with its near-infrared transient absorption. The Raman band due to the in-phase C C stretching mode of β-carotene in the S 2 s

The picosecond time-resolved polarized infrared absorption spectra of the photoexcited states of an oriented poly(p-phenylenevinylene) [-(C6H4CH=CH)n-, PPV] film have been recorded in the 3600-1050 cm(-1) region. The time-resolved photoinduced infrar

Time-dependent density functional theory (TD-DFT), together with the analytic calculation of gradients and numerical calculation of the Hessian matrix, has been applied to calculate the Raman, infrared, and fluorescence excitation spectra of trans-st

By using ATR and transmission probes combined with bundles of mid-infrared optical fibers, high-quality infrared spectra are observed for the radical anions of biphenyl and naphthalene in deuterated tetrahydrofuran solutions. The ATR and transmission

The fluorescence lifetimes decays and picosecond time-resolved fluorescence spectra were measured to investigate the dynamics of the excited state of sulforhodamine B (SRB) molecules adsorbed in the mono- and multilayered Langmuir-Blodgett (LB) films

The FT-Raman spectra oftrans-polyacetylene films doped lightly with iodine were obtained with the 1320-nm laser line. The observed Raman bands are attributed to positively charged domains created by acceptor doping. The observed Raman wavenumbers of

The difference of Raman spectra between lightly and heavily Na-doped trans-polyacetylene (trans-PA) was observed with the 1320 nm laser line, and these were discussed on the basis of the Raman spectra of the negatively charged anions Ph(CH) n Ph - [D

The laser-induced fluorescence excitation spectra of jet-cooled 4,4‘-dimethyl-trans-stilbene have been recorded, and the phenyl and methyl internal rotation levels have been assigned for the S0 and the S1(π,π*) electronic states. Dispersed fluore

BaMgAl 10 O 17 : Eu 2+ (BAM), an important blue phosphor of plasma display panel (PDP), has suffered from thermal degradation. Here, we describe the mechanism of thermal degradation of BAM–Ba–hexaaluminate (0.82BaO·6Al 2 O 3 ) in relation to the
