High-resolution coherent Raman spectroscopy of all three tritium-containing molecular hydrogen – T2, DT and HT – were performed to determine the ground electronic state fundamental Q-branch transition frequencies at accuracies of 0.0005 cm−1.
Intramolecular methyl–methyl coupling on Au (111) is explored as a new on-surface protocol for edge extension in graphene nanoribbons (GNRs). Characterized by high-resolution scanning tunneling microscopy, noncontact atomic force microscopy, and Raman spectroscopy, the methyl–methyl coupling is proven to indeed proceed at the armchair edges of the GNRs, forming six-membered rings with sp3- or sp2-hybridized carbons.
