1H detected proton-carbon correlation spectra for different types of biological systems studied without the need of deuteration 1. The left side shows a Cα-Hα dipolar correlation of microcrystalline GB1, while the right picture shows the same correlation acquired on a sedimented icosahedral nucleocapsid.

Inverse detected 1H-14N correlation as an HMQC type experiment2. You can see correlation peaks from various protons to 14N. This can help to elucidate e.g. pharmaceutical compounds. Data recorded in collaboration with Dinu Iuga, Facility Manager at the UK 850 MHz Solid-State NMR Facility at the University of Warwick.
