The interaction of titanium-carbon cluster fragments

Abstract

Covariance and correlation coefficient mapping techniques are utilized to investigate the formation mechanism of titanium carbon clusters in a laser vaporization source, and also to elucidate the details of fragmentation of these clusters under excitation with an intense femtosecond laser pulse (∼ 10 15 W/cm 2 at 120 fs). This study, and a previous investigation of the Coulomb explosion of ammonia clusters, demonstrates the potential which covariance mapping has in discerning the details of cluster formation and fragmentation processes. Particular attention is paid to the titanium metallocarbohedrene (Met-Car), Ti 8 C 12 .PACS. 36.40.Qv Stability and fragmentation of clusters -78.47.+p Time-resolved optical spectroscopies and other ultrafast optical measurements in condensed matter

“…Similar covariance mapping technique was also reported in IR studies [80]. The technique is still very popular in mass spectrometry [81][82][83][84][85]. 2D MS covariance mapping based on photo-ionization of clusters was reported [80,82].…”
