Strong Differential Photoion Circular Dichroism in Strong-Field Ionization of Chiral Molecules
نویسندگان
چکیده
We investigate the differential ionization probability of chiral molecules in strong-field regime as a function helicity incident light. To this end, we analyze fourfold bromochlorofluoromethane (CHBrClF) with subsequent fragmentation into four charged fragments and different dissociation channels singly ionized methyloxirane. By resolving for molecular orientation, show that photoion circular dichroism signal strength is increased by 2 orders magnitude.

Strong-field ionization of aligned molecules
Theoretical studies of strong-field ionization of molecules are impeded by the complexity of the molecular electronic structure. Up till now, full ab initio calculations of the alignmentdependent ionization are available only for H2 and H2. For larger molecules, despite a tremendous amount of experiments, no ab initio calculations are available, and the most widely used approaches to explain st...
متن کاملIonization Study of Isomeric Molecules in Strong-field Laser Pulses
Through the use of the technique of time-of-flight mass spectroscopy, we obtain strong-field ionization yields for randomly oriented 1,2-dichloroethylene (1,2-DCE) (C2H2Cl2) and 2-butene (C4H8). We are interested in studying the effect of conformal structure in strong-field ionization and, in particular, the role of molecular polarity. That is, we can perform strong-field ionization studies in ...
متن کاملCoulomb asymmetry in strong field multielectron ionization of diatomic molecules.
We measure the angular distribution of an electron emitted by a strong elliptically polarized two-color laser field from exploding doubly charged molecular nitrogen. This angular distribution is vastly different for emission of the electron from the up-field core of the molecule as compared to that from the down-field core. The emission from the down-field core leads to a slight rotation with r...
متن کاملStrong-field ionization of sputtered molecules for biomolecular imaging.
Photoionization of molecules sputtered from molecular thin films has been achieved using high field 125 fs pulses in the mid-IR spectral range. Using several model systems, we show that it is possible to significantly reduce molecular fragmentation induced by the laser field by increasing the photoionization wavelength. By examining the photoionization spectra as a function of wavelength, it is...
