Nagayama, K. Daigoku, Y. Kiyooka, K. Hashimoto Title: Laser induced emission spectra of polyyne molecules C2nH2 (n = 5–8) Journal: Chem. Phys. Lett, 446, 65-70, (2007); doi:10.1016/j.cplett.2007.08.057 Data: (diagram, table, disk): diagram, table Wavelength range: ~ 400 - 600 nm Resolution: Temperature: 298 K Temperature dependence: Pressure: Comments: Optical emission spectra. The emission spectra of C10H2 showed distinct peaks at 436 and 480 nm with a separation of ~ 2100 cm-1. Weak absorption features were also recorded in near-UV regions in shorter wavelengths to compare with the emission spectra. Author to whom correspondence should be addressed: (e-mail address):
