Summary
A new dataset, RTCONF55-16K, enables faster conformational analysis. Cost-efficient protocols like CENSO-light and CENSO-zero offer accurate relative free energy estimates with minimal error.
Area of Science:
- Computational Chemistry
- Molecular Modeling
Background:
- Conformational analysis is crucial for understanding molecular behavior.
- Existing methods can be computationally expensive.
- Accurate estimation of relative free energies is essential.
Purpose of the Study:
- To introduce RTCONF55-16K, a novel dataset for evaluating conformational analysis protocols.
- To develop and assess cost-efficient protocols for conformational analysis.
- To compare the accuracy and speed of new protocols against established methods.
Main Methods:
- Development of cost-efficient protocols (CENSO-light, CENSO-zero) based on the CENSO procedure.
- Utilizing the RTCONF55-16K dataset for benchmarking.
- Performing reference calculations to validate accuracy.
Main Results:
- The new protocols (CENSO-light, CENSO-zero) are 10-30 times faster than the original CENSO algorithm.
- The absolute error in relative free energy estimates is only 0.4-0.7 kcal/mol.
- The accuracy of the CENSO procedure was confirmed by reference calculations.
Conclusions:
- Economical and general-purpose protocols for conformational analysis have been developed.
- These protocols provide a favorable cost-accuracy compromise.
- RTCONF55-16K serves as a valuable resource for assessing conformational analysis techniques.

00:52¹H NMR of Conformationally Flexible Molecules: Temporal Resolution
829
At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

01:15¹H NMR of Conformationally Flexible Molecules: Variable-Temperature NMR
1.1K
The axial and equatorial protons in cyclohexane can be distinguished by performing a variable-temperature NMR experiment. In this process, except for one proton, the remaining eleven protons are replaced by deuterium. The deuterium substitution avoids the possible peak splitting caused by the spin-spin coupling between the adjacent protons. The remaining proton flips between the axial and equatorial positions.

02:18Conformations of Ethane and Propane
13.9K
In an organic molecule, free rotation about the carbon-carbon single bond results in energetically different conformers of the molecule. Due to this rotation, called the internal rotation, ethane has two major conformations — staggered and eclipsed.
Staggered conformation is a low energy and more stable conformation with the C-H bonds on the front carbon placed at 60°dihedral angles relative to the C-H bonds on the back carbon, leading to a reduced torsional strain. In staggered...

02:20Conformations of Butane
14.1K
Unlike ethane and propane that have only two major conformations, butane has more than two conformers. The staggered form of butane in which the bulky methyl groups on the two carbons are placed on opposite sides, that is, at a dihedral angle of 180°, is the lowest energy, most stable form — called the anti conformer. This conformation is stabilized due to the absence of steric repulsion between the largely spaced out methyl groups. The other two staggered conformations are...

02:11Conformations of Cyclohexane
12.4K
Cyclohexane does not exist in a planar form due to the high angle and torsional strain it would experience in the planar structure. Instead, it adopts non-planar chair and boat conformations.
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...

02:02Chair Conformation of Cyclohexane
14.6K
The chair conformation is the most stable form of cyclohexane due to the absence of angle and torsional strain. The absence of angle strain is a result of cyclohexane’s bond angle being very close to the ideal tetrahedral bond angle of 109.5° in its chair conformer. Similarly, the torsional strain is also absent owing to the perfectly staggered arrangement of bonds.
