Spectroscopy of isolated gramicidin peptides.
Many details of intrinsic properties of biomolecules are masked by elements of the biological environment, such as the solvent and intermolecular interactions. Separation of the interandExpand

Isomer discrimination of polycyclic aromatic hydrocarbons in the Murchison meteorite by resonant ionization.
We have used two-color resonant two-photon ionization (2C-R2PI) mass spectrometry to discriminate between isomers of polycyclic aromatic hydrocarbons in the Murchison meteorite. We measured theExpand

IR-UV double resonance spectroscopy of guanine-H2O clusters.
We present the IR-UV double resonance spectrum of guanine monohydrate in the region 3100 cm(-1) to 3800 cm(-1) along with the energies and frequencies of these structures calculated at theExpand

The mid-IR spectra of 9-ethyl guanine, guanosine, and 2-deoxyguanosine.
We present the mid-IR (400-1800 cm(-1)) spectra of 9-ethyl guanine, guanosine, and 2-deoxyguanosine measured by IR-UV double-resonance spectroscopy. We compare the recorded mid-IR spectra with theExpand

IR-UV double resonance spectroscopy of xanthine.
We present resonant two-photon ionization (R2PI), UV-UV, and IR-UV double resonance spectra of xanthine seeded in a supersonic jet by laser desorption. We show that there is only one tautomer ofExpand

Microhydration of Guanine base pairs.
We report spectroscopy of clusters of guanine base pairs with one and two water molecules. We recorded the vibronic spectra of the mass-selected GG(H2O) and GG(H2O)2 clusters using resonant twoExpand

Guanine-aspartic acid interactions probed with IR-UV resonance spectroscopy.
Double resonance spectroscopy of clusters of guanine with aspartic acid reveals geometries similar to patterns exhibited in DNA base pairs. In the spectral region of 32,800 cm(-1) to 35,500 cm(-1) weExpand

Au th or ' s pe rs on al co py Gas phase spectroscopy of the pentapeptide FDASV
IR–UV double resonance spectroscopy of the laser-desorbed, jet-cooled pentapeptide FDASV shows only one type of conformer in the gas phase. Comparison with computations at the B3LYP/6-31G** levelExpand
