Abstract
The present article is concentrated to study the vibrational properties of carbon nanotube through weak interaction method specially single walled carbon nanotube. SWNT acts as pure quntum elements in which electrons move in axial direction of the tube and it may decompose at temperature higher than 550. It is theoretically ensured that frequency of vibration of carbon nanotube tends to increase as the tube diameter decreases so as to resonant frequency set up in easier way. Originally vibrational frequency of carbon nanotube depends on chiral vector C and nanotube diameter . virtual calculation has been done to show the dependence of frequency on nanotube diameter in different order of atomicity (m, n). The length of nanotube is not arbitrarily rather with respect to nanotube diameter as if volume maintaining constant. The theoretical data have also been compared to Donnel thin shell theory where model deformation displacement are interpretated.
