A practical methodology to conduct the time-resolved fluorescence microscopy has been developed; the technique employs bursts of excitation pulses ( ≤ ms duration) gated by an electro-optic modulator from a 76 MHz ultrafast oscillator and enables i

We have developed a subpicosecond time-resolved fluorescence anisotropy (TRFA) that newly implements a photoelastic modulator to alternate the polarizations of an excitation laser light. The setup facilitates virtually simultaneous detection of the p

The ultrafast radiationless decay of photoexcited uracil and cytosine has been investigated by ab initio quantum chemical methods based on CIS and CR-EOM-CCSD(T) electronic energy calculations at optimized CIS geometries. The calculated potential ene

A line-by-line rotational analysis of a selected group of bands in the high-resolution A ˜ 1 A 2 ( n π ∗ ) ← X ˜ 1 A 1 fluorescence excitation spectrum has been carried out to derive the structure of thiophosgene in the A 1 A 2 ( n π ∗ ) or

One-photon excitation of the S0(X) thiophosgene to the S1(A) state, followed by photodepletion of the S1→S0 fluorescence by Sn (n=2,3)←S1 excitation, by another photon, reveals the presence of a dark S3(C) state in the vicinity of the B1A1(ππ*)

The collision-free S 1 [A 1 A 2 (nπ*)] thiophosgene, with small ( 9284 cm - 1 ) excess vibrational energies, does not exhibit radiationless transitions to bound electronic states (So and T 1 ), as evidenced by intense A → X fluorescence with nearl
The time-dependent DFT calculations for the low-lying excited electronic states of 4- and 3-di- tert -butylaminobenzonitrile, and 2,4,6-tricyano- N , N -dimethylaniline and 2,4,6-tricyanoaniline have been performed to investigate the mechanism of pho

The solvent-polarity dependence and temporal characteristics of the transient absorption of 4-(dimethylamino)benzonitrile, DMABN, and 4-(dimethylamino)benzethyne, DMABE, demonstrate the presence of the πσ*-state absorption at about 700 nm and the

The structure and excited state dynamics of jet-cooled 9,9′-bianthryl (BA) and its 1:1 van der Waals (vdW) complexes with Ne, Ar, and H2O were studied using rotational coherence spectroscopy (RCS). For a free BA molecule, the magnitude and persiste

The excited state dynamics of 9,9'-bianthryl (BA) clusters with H2O and Ar have been studied by measuring their time-resolved fluorescence at selected emission wavelengths. We have found that the photoexcitation of the BA–H2O clusters yields a char
