Mass spectra of quarkonium systems can be described by different
phenomenological potentials. In the present work, the {\color{black}resonance}
states of heavy quarkonium like (ccΛ and bbΛ) are considered as
the rovibrational states. We study a parameterized rovibrational model derived
from the empirical solution of the nonrelativistic Schr\"{o}dinger equation
with Morse potential, the corrections are composed of colour hyperfine
interaction and spin-orbit interaction of mesons. We {\color{black}obtain} the
high excited state mass spectra of charmonium and bottomonium comparing the
results in reasonable agreement with the present experimental data.Comment: 6 pages, 4 figure
