We fill single‐walled carbon nanotubes with a mean diameter of 1.7 nm with ferrocene and perform in situ studies on time‐dependent inner tube growth by Raman spectroscopy. The evolution of Raman spectra dependent on annealing time is analyzed. It is found that inner tube growth does not follow a simple exponential model. The growth rates of inner tubes are calculated within a suggested growth model. It is found that the growth rate is higher for smaller diameter inner nanotubes.
