Electron spin resonance experiments in the quasi-1D S=1/2 antiferromagnetK$_2$CuSO$_4$Cl$_2$ reveal opening of a gap in absence of magnetic ordering, aswell as an anisotropic shift of the resonance magnetic field. These features ofmagnetic excitation spectrum are explained by a crossover between a gappedspinon-type doublet ESR formed in a 1D antiferromagnet with uniformDzyaloshinskii-Moriya interaction and a Larmor-type resonance of a quasi-1DHeisenberg system
