Question

Peak frequency (ppm)	Peak multiplicity (s,d,etc.)	Peak integration(Number of Protons)
8.67	d, J =4.0 Hz
8.20	d, J 8.7 Hz
8.07	d, J=7.6 Hz
7.88	ddd, J=1.5,7.6,7.6 Hz
7.62	d, J=8.9 Hz
7.54	m(multiplet)
5.38	dd, J=7.4, 3.6 Hz
4.79	s
3.63	dd, J=3.6,16.8
3.55	dd, J=8.5, 16.8

What is the peak integration number? This is 1' H NMR spectrum of 3-hydroxy-3-(4-nitrophenyl)-1-(2-pyridyl)-1-propanone
