Many experiments of resonant Raman spectroscopy have been carried out to successfully assign the radial breathing mode frequency of the inner and outer tube of double walled carbon nanotube. Experimental values show clear indication that these frequencies depend heavily on inter tube interaction. All the previous efforts to establish a relation between RBM frequency and diameter have not taken the inter-tube distance factor into account. Here, for the first time an empirical relation between the RBM frequency and diameter of the tubes is presented for DWNT taking the inter-tube interaction effect into account which can accurately predict the diameter of both, the inner and outer tube from the RBM frequency. This relation can be significant in future and will open a new door for finding the chirality of each tube in DWNT.
