✦ Synopsis
The first known T n ~ T 1 absorption spectra of a potassium salt of poly [4,6-decadiyn-l,10-diol-bis(carboxyl-methyl-urethane)] at three different pH values (7.5, 7.1, and 6.0) were measured over a wavelength region of 400-900 nm by use of a Q-switched Nd : YAG laser. The T n ~ T 1 spectra and their lifetimes were found to be relatively insensitive to pH.
