Structural rearrangement in gas phase niobium carbide clusters, NbnC3 and NbnC6

- Focused and slightly defocused ablation laser for graphite target was used.
- Broad and NbnC3k0/+ rich distributions were observed.
- Neutral clusters consist of the same isomers in the two conditions.
- The lowest energy isomer has the Nb and C atoms well mixed.
- Structural rearrangement of the clusters is consistent with the DFT calculations.
