Ultrafast transient absorption studies are reported for high-aspect-ratio gold nanorods that were fabricated by electrochemical deposition in polycarbonate templates. The nanorods are 60 nm in diameter with distribution of lengths of up to 6 μm. The

Reorientation and vibrational energy relaxation times have been measured by ultrafast transient polarization IR spectroscopy for the antisymmetric stretching band in the 2000–2200 cm−1 region of pseudohalide ions, N3−, NCO−, and NCS−, confi

Vibrational energy relaxation (VER) times have been measured by ultrafast infrared spectroscopy near 2000 cm−1 for the antisymmetric stretching ν3 band of azide ion in water pools of nonionic reverse micelles (RM). The water pool radii were varied

The photodissociation dynamics of the 3s Rydberg state of three ketones (CH3CO–R, R=C2H5, C3H7, and iso-C4H9) and the ensuing dissociation of the nascent acetyl radical following 195 nm excitation were investigated by ultrafast photoionization spec

We report an ultrafast 400 nm pump–IR probe study of Mn 2 (CO) 10 photochemistry in cyclohexane and isopropanol at room temperature. While both Mn 2 (CO) 9 and Mn(CO) 5 are produced with UV dissociation, long wavelength excitation at 400 nm yields

Ultrafast surface second harmonic generation (SHG) studies are reported for several oxazine dyes at the air/water interface. As we demonstrated previously [J. Phys. Chem. B 2001, 105, 3062] in our steady-state SHG studies of aqueous oxazine dye solut

Ultrafast photoionization spectroscopy has been used to measure excited state lifetimes for several ketones excited near 193 nm. The decay times for aliphatic ketones are between 2 and 9 ps, which are consistent with 3s Rydberg state predissociation

The secondary dissociation dynamics of the methylsulfonyl radical following the photodissociation near 193 nm of methylsulfonyl chloride and methylsulfonyl ethanol has been studied using femtosecond mass-resolved photoionization spectroscopy. The pri

Unimolecular decomposition rates for acetyl radical following the photodissociation of acetyl cyanide and acetic acid near 193 nm have been studied using ultrafast mass-resolved photoionization spectroscopy. In both cases, the parent decays with an i
