Tip

Code for NMR example Copy and paste the following code into your first jupyter notebook to produce the plot shown in above screenshot

from hqs_nmr_parameters import examples
from hqs_nmr import NMRCalculationParameters, calculate_spectrum
from matplotlib import pyplot as plt
print(f"Available moleucules: {examples.molecules.keys}")
molecule_name = '1,2,4-trichlorobenzene'
molecule_parameters = examples.molecules[molecule_name]
fig, ax = plt.subplots(figsize=(10, 6))
for field_T in [1, 5, 10]:
    result = calculate_spectrum(molecule_parameters, NMRCalculationParameters(field_T=field_T))
    ax.plot(result.spectrum.omegas_ppm, result.spectrum.intensity, label=f"B={field_T}T")
plt.legend()
ax.set_xlabel(r"$\delta$ [ppm]")
ax.set_ylabel("Intensity, arb. units")
ax.set_title(f"Spectrum of {molecule_name}")
plt.show()

Caution

Costs and shutting down the server After starting your server your HQ$ balance will be debited until you shutdown the server. After 6 hours of inactivety we will automatically shut down your server and stop debiting your HQ$ balance.

To shutdown the server click File-->Hub Control Panel-->Stop My Server. This will shutdown your server and your HQ$ balance will no longer be debited.
