Distance Magic and Distance Antimagic Labeling of Some Product Graphs

2020
Distance magic graph admits a distance magic labeling, whereas the distance antimagic graph admits a distance antimagic labeling. This chapter discusses the existence of distance magic labeling and distance antimagic labeling for a specific function. It considers that all graphs with a specific vertex set and a specific edge set are finite and simple ...

Distance magic labelings of graphs

Australas. J Comb., 2003
Authors define 1-vertex-magic labelling of a graph \(G=(V,E)\) as a bijection \(f\colon \{1,2,\dots, |V|\} \to V\) such that for any two vertices \(u,v \in V\), \(\sum_{x\in N(u)}f(x)=\sum_{y\in N(v)}f(y)\). The authors solve the existence problem of 1-vertex-magic labellings on complete bipartite, tripartite and regular multipartite graphs.

A $$\varGamma $$-magic Rectangle Set and Group Distance Magic Labeling

2015
A \(\varGamma \)-distance magic labeling of a graph \(G = (V, E)\) with \(|V| = n\) is a bijection \(\ell \) from V to an Abelian group \(\varGamma \) of order n such that the weight \(w(x) =\sum _{y\in N_G(x)}\ell (y)\) of every vertex \(x \in V\) is equal to the same element \(\mu \in \varGamma \) called the magic constant.

On distance magic labeling of graphs

2009
Summary: Distance magic labeling of a graph of order \(n\) is a bijection \(f:V\to\{1,2,\dots,n\}\) with the property that there is a positive integer constant \(k\) such that for any vertex \(x\), \(\sum_{y\in N(x)}f(y)=k\), where \(N(x)\) is the set of vertices adjacent to \(x\).

A magic-angle-spinning NMR method for H1–H1 distance measurement using coherent polarization transfer in C13-labeled organic solids

The Journal of Chemical Physics, 2008
We have developed a theory for H1–H1 distance measurements from the direct polarization transfer in C13-labeled solids under magic-angle spinning. The polarization transfer caused by the H1–H1 dipolar interactions was analyzed with zeroth-order average Hamiltonian for a H1–C13–C13–H1 spin system in the frame modulated by C13–H1 dipolar interactions and

Band-Selective Carbonyl to Aliphatic Side Chain ¹³C−¹³C Distance Measurements in U-¹³C,¹⁵N-Labeled Solid Peptides by Magic Angle Spinning NMR

Journal of the American Chemical Society, 2004
We describe three-dimensional magic angle spinning NMR experiments that enable simultaneous band-selective measurement of the multiple distance constraints between carbonyl and side chain carbons in uniformly 13C,15N-labeled peptides. The approaches are designed to circumvent the dipolar truncation and to allow experimental separation of the multiple ...

CHAPTER 3. ¹³C–¹³C Distance Measurements by Polarization Transfer Matrix Analysis of ¹³C Spin Diffusion in a Uniformly ¹³C-Labeled Molecular Complex under Magic Angle Spinning

2014
Spin diffusion of 13C polarization in NMR provides 13C−13C distances under magic angle spinning over a broad spectral width. However, there are difficulties in obtaining the distances accurately in uniformly 13C-labeled molecular complexes in solids. Effects of the weak long-range couplings are suppressed by strong short-range couplings.
