Dispersed fluorescence (DF) spectra of 1-propoxy, 1-butoxy, 2-propoxy, and 2-butoxy radicals have been observed under supersonic jet cooling conditions by pumping different vibronic bands of the B-X laser induced fluorescence excitation spectrum. The DF spectra were recorded for both conformers of 1-propoxy, three conformers of the possible five of 1-butoxy, the one possible conformer of 2-propoxy, and two conformers of the possible three of 2-butoxy. Analysis of the spectra yields the energy separations of the vibrationless levels of the ground X and low-lying A electronic state as well as their vibrational frequencies. In all cases, the vibrational structure of the DF spectra is dominated by a CO stretch progression yielding the nuCO stretching frequency for the X state and in most cases for the A state. In addition to the experimental work, quantum chemical calculations were carried out to aid the assignment of the vibrational levels of the X state and for some conformers the A state as well. Geometry optimizations of the different conformers of the isomers were performed and their energy differences in the ground states were determined. The results of the calculation of the energy separations of the close-lying X and A states of the different conformations are provided for comparison with the experimental observations.

Investigations of the air-liquid interface of aqueous salt solutions containing ammonium (NH(4)(+)) and sulfate (SO(4)(2-)) ions were carried out using molecular dynamics simulations and vibrational sum frequency generation spectroscopy. The molecular dynamics simulations show that the predominant effect of SO(4)(2-) ions, which are strongly repelled from the surface, is to increase the thickness of the interfacial region. The vibrational spectra reported are in the O-H stretching region of liquid water. Isotropic Raman and ATR-FTIR (attenuated total reflection Fourier transform infrared) spectroscopies were used to study the effect of ammonium and sulfate ions on the bulk structure of water, whereas surface sum frequency generation spectroscopy was used to study the effect of these ions on the interfacial structure of water. Analysis of the interfacial and bulk vibrational spectra reveal that aqueous solutions containing SO(4)(2-) perturb the interfacial water structure differently than the bulk and, consistent with the molecular dynamics simulations, reveal an increase in the thickness of the interfacial region.

Untersuchungen der Luft-Fl&uuml;ssigkeit-Schnittstelle des w&auml;ssrigen Salzl&ouml;sungen mit Ammonium (NH(4)(+)) und Sulfat (SO(4)(2-))-Ionen wurden durchgef&uuml;hrt mit Molekulardynamik-Simulationen und Schwingungs-Summe-Frequenz-Generierung-Spektroskopie. Die Molekulardynamik-Simulationen zeigen, dass die vorherrschende Wirkung der SO(4)(2-) Ionen, die stark von der Oberfl&auml;che abgesto&szlig;en werden, erh&ouml;hen Sie die St&auml;rke der Grenzfl&auml;chenspannung Region. Die Schwingungs-Spektren gemeldet sind in der O-H-Dehnung-Region von flie&szlig;endem Wasser. Isotrope Raman und ATR-FTIR (abgeschw&auml;chte Totalreflexion Fourier-Transform-Infrarot) SPEKTROSKOPIEN verwendet wurden, um die Wirkung von Ammonium- und Sulfat-Ionen auf der Massen-Struktur des Wassers, zu studieren, w&auml;hrend Oberfl&auml;che Summe Frequenz Generierung Spektroskopie verwendet wurde, um die Wirkung der diese Ionen auf der Grenzfl&auml;chenspannung Struktur des Wassers zu studieren. Analyse der die Grenzfl&auml;chenspannungen und Massen-Schwingungs-Spektren zeigen, dass w&auml;ssrige L&ouml;sungen mit SO(4)(2-) verl&auml;ngern die Grenzfl&auml;chenspannung Wasser-Struktur anders als der Hauptteil und konsistent mit der Molekulardynamik-Simulationen, zeigen einen Anstieg der Dicke der Grenzfl&auml;chenspannung Region.
