Hydrogen storage properties of copper and silver exchanged zeolite SSZ-13

Copper and silver cation-exchanged zeolite SSZ-13 present an interesting opportunity to study the mechanism of interaction of adsorbate gases, primarily hydrogen (H2), with the ion-exchange sites in zeolites as there is only one type of cation site, in con ...

Quantitative State-Selective Spectroscopy of Water Below and Above the First Dissociation Limit

Maxim Grechko

We use triple resonance vibration overtone spectroscopy to characterize quantum states of water with up to 19 quanta of stretching vibration – the last stretching state below dissociation. State-selectivity, offered by the triple resonance in conjunction w ...

Detection Of Vibrationally Excited Co In Irc+10216

Sandra Bruenken

Using the Submillimeter Array we have detected the J = 3-2 and 2-1 rotational transitions from within the first vibrationally excited state of CO toward the extreme carbon star IRC+10216 (CW Leo). The emission remains spatially unresolved with an angular r ...

Polycyclic Aromatic Hydrocarbons (PAHs) are widely accepted as the carriers of the Aromatic Infrared Bands (AIBs), but an unambiguous identification of any specific interstellar PAH is still missing. For polar PAHs, pure rotational transitions can be used ...

LABORATORY DETECTION OF HOCN AND TENTATIVE IDENTIFICATION IN Sgr B2

Sandra Bruenken

The rotational spectrum of cyanic acid, HOCN, has been detected in the centimeter-wave band in a molecular beam by Fourier transform microwave spectroscopy and in the millimeter-wave band by conventional spectroscopy in a low-pressure laboratory discharge. ...

Redistribution of pump power and impairments in gain-equalized distributed fiber Raman amplifiers due to four-wave mixing and parametric amplification

Marcelo Alfonso Soto Hernandez

In this work, by using a comprehensive numerical model which rigorously describes the interaction between stimulated Raman scattering (SRS) and four-wave mixing (FWM), we verify that FWM processes, including depletion and parametric gain, generate a redist ...

Impairments in Gain-Equalized Distributed Fiber Raman Amplifiers due to Four-Wave Mixing and Parametric Amplification Processes

Marcelo Alfonso Soto Hernandez

In this work, by means of numerical simulations, we verify that four‐wave mixing (FWM) processes, including depletion and parametric gain, generate a redistribution of pump power in distributed fiber Raman amplifiers (DFRAs). As a consequence of pump‐pump ...

Dipole moments of HDO in highly excited vibrational states measured by Stark induced photofragment quantum beat spectroscopy

Thomas Rizzo, Patrice Theulé

We report here a measurement of electric dipole moments in highly vibrationally excited HDO molecules. We use photofragment yield detected quantum beat spectroscopy to determine electric field induced splittings of the J=1 rotational levels of HDO excited ...

Rotational and torsional analysis of the OH-stretch third overtone in (CH3OH)-C-13

Thomas Rizzo

We record double resonance spectra of the 4nu(1) band of jet-cooled C-13-methanol using single rotational state selection in the nu(1) fundamental and subsequent promotion of the selected molecules to the fourth vibrational level. We then detect transition ...
