  We analyse various microscopic properties of the nematic fractional quantum
Hall effect (FQHN) in the thermodynamic limit, and present necessary conditions
required of the microscopic Hamiltonians for the nematic FQHE to be robust.
Analytical expressions for the degenerate ground state manifold, ground state
energies, and gapless nematic modes are given in compact forms with the input
interaction and the corresponding ground state structure factors. We relate the
long wavelength limit of the neutral excitations to the guiding center metric
deformation, and show explicitly the family of trial wavefunctions for the
nematic modes with spatially varying nematic order near the quantum critical
point. For short range interactions, the dynamics of the FQHN is completely
determined by the long wavelength part of the ground state structure factor.
The special case of the FQHN at $\nu=1/3$ is discussed with new theoretical
insights from the Haffnian parent Hamiltonian, leading to a number of rigorous
statements and experimental implications.
