Heteronuclear correlation (HETCOR) is {critical|crucial|vital|essential|important} to {obtain|acquire|get|receive} structural {information|info|details|data|facts|information and facts} in solid-state nuclear magnetic resonance (NMR). We propose novel frequency-selective Heteronuclear correlation (FS-HETCOR) experiments to selectively {enhance|improve|boost} the inter-atomic correlations of interest. FS-HETCOR relies on heteronuclear selective phase-optimized recoupling (SPRx), {which is|that is|which can be} frequency-selective in heteronuclear recouping {without|with out|without having|with no|devoid of|without the need of} {using|utilizing|making use of|employing|working with|applying} selective pulses. {Compared to|In comparison to|In comparison with|When compared with} {regular|normal|typical|standard|common|frequent} HETCOR, FS-HETCOR selectively enhances the {desired|preferred} heteronuclear correlations by a {factor|aspect|element|issue} of {up to|as much as} {5|five} and suppresses the {unwanted|undesirable} ones to 10% as demonstrated in 1H-19F and 1H-13C experiments {under|below|beneath} {fast|quick|quickly|rapidly|rapid|speedy} magic-angle spinning (MAS). {Moreover|Furthermore|In addition|Additionally}, FS-HETCOR can theoretically be applied at arbitrary MAS {rates|prices} by {utilizing|using} {various|numerous|different|a variety of|several|many} SPRx schemes.
