| Abstract: | In this paper, the spin-dependent structure functions of nucleon g
1, and photoabsorption cross sections σ1/2, σ3/2 and σT in the resonance region are estimated based on the constituent quark model and the properties of the five phenomenological
Breit-Wigner resonances P

11(1535), D
13(1520), P
11(1440), and F
15(1680). Our results are compared to the recent E143 data of the polarized structure functions g

2=1.2 GeV2 and the data of the total inclusive photoabsorption cross sections.
