Coulomb Explosion Imaging as a Tool to Distinguish Between Stereoisomers
Published on: August 18, 2017
Summary
A new dynamic stereovisometry method and device (Stereovisotest) accurately measure stereoscopic vision thresholds from age 4. Normative data reveal age-related changes in stereoscopic perception, with potential for vision training.
Area of Science:
- Ophthalmology
- Vision Science
- Biomedical Engineering
Background:
- Stereoscopic vision is crucial for depth perception and visual tasks.
- Assessing stereoscopic vision accurately across different age groups is essential for understanding visual development and function.
- Existing methods may lack the precision or dynamic capabilities to fully evaluate stereoscopic capabilities.
Purpose of the Study:
- To introduce an original method of dynamic stereovisometry and a device (Stereovisotest) for examining stereoscopic vision.
- To establish age-specific normative data for stereoscopic thresholds in a large population sample.
- To investigate the potential for training and improving stereoscopic vision.
Main Methods:
- Development of a novel dynamic stereovisometry technique and the Stereovisotest device.
- Testing of 1810 subjects aged 4 to 60 with normal binocular vision to determine stereoscopic thresholds.
- Application of the Stereovisotest for vision assessment and training in individuals, including those with professions requiring precise vision.
Main Results:
- The Stereovisotest accurately measures stereoscopic thresholds (positive and negative) from age 4, with precision to 1 second of arc.
- Mean stereoscopic thresholds were established: 80 arc seconds (4-6 years), decreasing to 45 arc seconds (21-40 years), and increasing to 60 arc seconds (by age 60).
- Training with the Stereovisotest demonstrated the possibility of improving stereoscopic perception thresholds.
Conclusions:
- Dynamic stereovisometry using the Stereovisotest provides a precise and reliable method for assessing stereoscopic vision across a wide age range.
- Normative data highlight significant age-related variations in stereoscopic acuity.
- The Stereovisotest is effective for vision training, showing potential to enhance stereoscopic capabilities to physiological levels.

Stereoisomerism
Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

Isomerism
Isomers are molecules with the same molecular formula but different structural arrangements. Isomers can be further classified into constitutional isomers and stereoisomers. Constitutional isomers differ in the connectivity of their constituent atoms. For example, 2-butanol and diethyl ether are constitutional isomers, as they have the same chemical formula, C4H10O, but differ in the connectivity of the carbon and oxygen atoms. Constitutional isomers have different physical and chemical...
Stereoisomers
On the basis of mirror symmetry, stereoisomers of an organic molecule can be further classified into diastereomers and enantiomers. Diastereomers are stereoisomers that are not mirror images of each other. Substituted alkenes, such as the cis and trans isomers of 2-butene, are diastereomers, as these molecules exhibit different spatial orientations of their constituent atoms, are not mirror images of each other, and do not interconvert. Here, the interconversion is suppressed due to restricted...
Stereoisomerism of Cyclic Compounds
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the molecular symmetry and stereoisomerism of cyclic compounds. 1,2-Dimethylcyclohexane is used as a case study to evaluate the possible number of stereoisomers. Here, given the multiple (n = 2) chiral centers, there are 2n = 4 possible configurations that lack a plane of symmetry, as the ring skeleton exists in a non-planar chair conformation. In addition,...
Prochirality
The concept of prochirality leads to the nomenclature of the individual faces of a molecule and plays a crucial role in the enantioselective reaction. It is a concept where two or more achiral molecules react to produce chiral products. A typical process is the reaction of an achiral ketone to generate a chiral alcohol. Here, the achiral reactant reacts with an achiral reducing agent, sodium borohydride, to generate an equimolar mixture of the chiral enantiomers of the product. For example, an...
Diels–Alder Reaction Forming Cyclic Products: Stereochemistry
The Diels–Alder reaction is one of the robust methods for synthesizing unsaturated six-membered rings. The reaction involves a concerted cyclic movement of six π electrons: four π electrons from the diene and two π electrons from the dienophile.
