Research Interests:

The Douberly research group has made significant contributions to the development of spectroscopic techniques designed for the helium nanodroplet isolation method.  They have employed this methodology to address a diverse set of fundamental problems in chemical physics.  The low temperature (0.4 K) and rapid cooling associated with helium droplets provides a perfectly suited medium to isolate and spectroscopically probe transient species, such as molecular radicals and carbenes.  Reactants sequentially added to helium droplets are often stabilized in high-energy, metastable configurations on the potential energy surface.  Single and double resonance infrared (IR) laser spectroscopic techniques are used to probe the structural and dynamical properties of these systems, often with sufficiently high resolution to resolve rotational fine structure. 

            Continuous, effusive pyrolysis sources of molecular radicals and carbenes have been optimized for doping helium nanodroplets, and several spectroscopic studies have been reported which describe the fundamental chemical physics of helium-solvated small radicals and carbenes. The methyl,1 ethyl,2 vinyl,3 propargyl,4 allyl5 and hydroxyl6 radicals have been probed, as have the hydroxycarbene7 and dihydroxycarbene8 systems.  These reports provided fundamental insights into the spectroscopy of these species and the interactions of these systems with the helium environment.  Rotational and vibrational state-dependent line broadening,1-3 dynamically-induced anomalous lambda doubling,6,9 and the solvent effect on tunneling dynamics3 are examples of the fundamental chemical physics that have been probed in these studies.  Moreover, recent Stark spectroscopy measurements of hydrogen bonded complexes involving the hydroxyl radical (OH-C2H2, OH-C2H4, and OH-H2O) have been interpreted via spectroscopic models developed by Douberly, which employ the spherical tensor operator formalism to account for the Stark effect in molecules possessing partially quenched electronic angular momentum.10,11 

            The Douberly group has leveraged the sequential pick-up technique developed by Scoles to investigate the mechanisms associated with several key elementary atmospheric and combustion reactions carried out inside low temperature helium droplets.  The rational for these studies is that spectroscopic measurements carried out downstream from the pick-up zones are capable of identifying the structural configuration of key intermediates along the reaction path, along with the associated product branching ratios.  The outcome of low temperature reactions involving hydrocarbon radicals and O2,4,5,12 or the hydroxyl radical (OH) and O2,13 have been probed with this methodology.  For example, a series of studies on the OH + O2 helium-mediated reaction revealed the barrierless formation of trans-HOOO,13-15 which was inconsistent with theoretical studies that had predicted a large entrance channel barrier above the reactant asymptote.  Higher level multireference configuration interaction computations of this system carried out by others confirmed the barrierless reaction path implied by Douberly’s experiments.  IR laser Stark spectroscopy of trans-HOOO revealed inertial components of the permanent electric dipole moment that were inconsistent with computations at the equilibrium geometry, consistent with a floppy species undergoing large-amplitude torsional motion.15  These experimental dipole components provided a stringent benchmark for theoretical computations of the ground state wavefunction, which eventually resulted in definitive computations of the dissociation energy and atmospheric abundance of this species.15

            Measurements have been reported in which dipeptides,16 ionic liquids17 or mixed acid-water clusters17,18 are assembled within helium droplets.  A two-stage oven source was developed which allowed for high-precision measurements of the gas-phase interconversion thermodynamics of the model di-peptide N-acetylglycine methylamide.16  Polarization spectroscopy of the ionic liquid 1‑Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide revealed a dipole moment of ~12 Debye, confirming definitively that these types of systems evaporate as intact ion-pairs.17  IR laser spectroscopy was used to probe the evolution of the spectral signatures associated with the formation and trapping of non-equilibrium (HCl)n-(H2O)m cluster geometries.18,19  This study was reported in collaboration with Andrey Vilesov and provided critical insights into controversial previous measurements of the onset of acid ionization in small acid-water clusters.  Most recently, a paper on the formation of exotic hydrogen-bonded water networks in helium droplets was published in the Journal of the American Chemical Society.20   The range of systems studied during Douberly’s independent career is both a testament to the versatility of the helium droplet method and the creativity of his research group.
