A geometric model for the [2]catenanes was derived that approximates the macrocycles by circles and takes into account the topological constraint. ...For the small-sized catenane, moderate interaction between the unsaturated sections of the macrocycles in chloroform is ind

EPR characterization of Mn(ii) complexes for distance determination with pulsed dipolar spectroscopy.
Keller K, Zalibera M, Qi M, Koch V, Wegner J, Hintz H, Godt A, Jeschke G, Savitsky A, Yulikov M. Keller K, et al. Among authors: godt a. Phys Chem Chem Phys. 2016 Sep 14;18(36):25120-25135. doi: 10.1039/c6cp04884f. Phys Chem Chem Phys. 2016. PMID: 27711532
Mn(ii)-Mn(ii) distances are computed from RIDME data of Mn-rulers consisting of two Mn-PyMTA complexes connected by a rodlike spacer of defined length. Level crossing effects seem to have only a weak influence on the distance distributions computed from this set of …

Computing distance distributions from dipolar evolution data with overtones: RIDME spectroscopy with Gd(iii)-based spin labels.
Keller K, Mertens V, Qi M, Nalepa AI, Godt A, Savitsky A, Jeschke G, Yulikov M. Keller K, et al. Among authors: godt a. Phys Chem Chem Phys. 2017 Jul 21;19(27):17856-17876. doi: 10.1039/c7cp01524k. Epub 2017 Jun 29. Phys Chem Chem Phys. 2017. PMID: 28660955
As previously proposed, we account for these overtones by using a modified kernel function in Tikhonov regularization analysis. This paper analyzes the performance of such an approach on a series of model compounds with the Gd(iii)-PyMTA complex serving as paramagne …

Dalaloyan A, Qi M, Ruthstein S, Vega S, Godt A, Feintuch A, Goldfarb D. Dalaloyan A, et al. Among authors: godt a. Phys Chem Chem Phys. 2015 Jul 28;17(28):18464-76. doi: 10.1039/c5cp02602d. Phys Chem Chem Phys. 2015. PMID: 26108866
These are a consequence of neglecting the pseudo-secular term in the dipolar Hamiltonian during the data analysis, as is outlined in a theoretical treatment. At distances of 3.4 nm and above, disregarding the pseudo-secular term leads to a broadening of a

This requires a compromise between sensitivity and resolution to be made prior to the measurement, so that optimum data are only obtained if the magnitude of the dipole-dipole coupling is known beforehand to a good approximation. ...These problems are overcome by …
