Laser-induced fluorescence of matrix-isolated HCCCCCN+ and HCCCCCCCN+
Chemical Physics Letters, 1995Abstract The cyanodiacetylene (HC5N+) and cyanotriacetylene (HC7N+) cations were produced in a pulsed supersonic discharge through a dilute cyanoacetylene (HC3N) neon mixture, and isolated in solid neon at 5–7 K. The A2Π-X2Π transitions of these cations were investigated by means of laser excitation and Fourier-transform emission spectroscopy.

It is discovered that at low temperatures the characteristic phase separation time constant of solid mixtures ??He in ???He depends on temperature non-monotonically (has a minimum). It means that the velocity of the substance transport slows down at very low temperature and the corresponding values of the effective diffusion coefficient also depend non-
