In isodoublet sector with $I=1/2$, with the same reasonable parameters the interaction produces seven molecular states, a state near $ \\Sigma_bB$ threshold with spin parity $J^P=1/2^-$, a state near $\\Sigma^*_bB$ threshold with $3/2^-$, two states near $\\Sigma_bB^*$ threshold with $1/2^-$ and $3/2^-$, and three states near $\\Sigma_b^*B^*$ threshold with $1/2^-$, $3/2^-$, and $5/2^-$.
