|February 7, 2018
Summary
We developed a single-shot molecular orbital tomography (MOT) technique using orthogonal two-color (OTC) fields. This breakthrough allows real-time imaging of electron orbital dynamics, overcoming previous multi-shot limitations.
Area of Science:
- Quantum chemistry
- Attosecond science
- Molecular imaging
Background:
- Molecular orbital tomography (MOT) utilizes high-order harmonic generation to study electron dynamics.
- Current MOT methods require multi-shot measurements, limiting real-time observation of chemical reactions and electron orbital evolution.
Purpose of the Study:
- To develop a single-shot MOT scheme for real-time imaging of molecular electron dynamics.
- To overcome the limitations of multi-shot measurements in high-resolution molecular imaging.
Main Methods:
- Implementation of an orthogonal two-color (OTC) laser field scheme.
- Utilizing the two-dimensional manipulation of electron motion within OTC fields for tomographic reconstruction.
Main Results:
- Demonstration of single-shot molecular orbital imaging capability.
- Achieved tomographic imaging of molecular orbitals with a single measurement.
Conclusions:
- The developed single-shot MOT scheme with OTC fields enables real-time tracking of molecular electron dynamics.
- This advancement paves the way for attosecond temporal and sub-Ångström spatial resolution studies of chemical processes.

An atomic orbital represents the three-dimensional regions in an atom where an electron has the highest probability to reside. The radial distribution function indicates the total probability of finding an electron within the thin shell at a distance r from the nucleus. The atomic orbitals have distinct shapes which are determined by l, the angular momentum quantum number. The orbitals are often drawn with a boundary surface, enclosing densest regions of the cloud.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Conjugated dienes have lower heats of hydrogenation than cumulated and isolated dienes, making them more stable. The enhanced stabilization of conjugated systems can be understood from their π molecular orbitals.
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...

According to the molecular orbital (MO) model, benzene has a planar structure with a regular hexagon of six sp2 hybridized carbons. As shown in Figure 1, each carbon is bonded to three other atoms with C–C–C and H–C–C bond angles of 120°. The C–H bond length is 109 pm, and the C–C bond length is 139 pm which is midway between the single bond length of sp3 hybridized carbons (154 pm) and sp2 hybridized carbons (133 pm).
