Nicotine, molecular formula

B Nicotine is a diamino compound isolated from dried tobacco leaves. Nicotine has two rings and M + = 162.1157 by high-resolution mass spectrometry. Give a molecular formula for nicotine, and calculate the number of double bonds. 

M.10 Nicotine, the stimulant in tobacco, causes a very complex set of physiological effects in the body. It is known to have a molar mass of 162 g-mol. When a sample of mass 0.385 g was burned, 1.072 g of carbon dioxide, 0.307 g of water, and 0.068 g of nitrogen were produced.

A series of EPR measurements (along with optical and magnetic susceptibility studies) in lanthanide nicotinate dihydrates (RND) was carried out by Baker et al. (1986a,b, 1987, 1988, 1991a,b). These compounds with stoichiometric formula [R(C5H4NC02)3(H20)2]2 have a dimeric molecular crystal structure with space group P2i/c. Two lanthanide ions in a dimeric pair with a separation near 4.3 A are related by inversion symmetry but there is no symmetry at each R site. The smallest distance between inversion centers is about 9.5 A.
