heteronuclear single quantum correlation with additional TOCSY transfer

initialism: HSQC-TOCSY
https://doi.org/10.1351/goldbook.08359
Variant of the heteronuclear single quantum correlation (HSQC) experiment that shows correlations from a heteronucleus (e.g., \(\ce{^{13}C}\)) to not only its directly bound \(\ce{^{1}H}\) but also to all other \(\ce{^{1}H}\) nuclei within the spin system.
