Abstract

The photophysical properties of stacked G-tetrads in diverse systems, including concentrated solutions of 5′-guanosine monophosphate (5′-GMP), polyguanylic acid (poly(G)) and the G-rich oligodeoxynucleotide sequence characteristic of human telomeric DNA, are probed by ps-TRIR and compared to those of the monomeric 5′-GMP.
