“…Moreover they are many trapping sites due to the cage effect of the matrix which makes the analysis complex. The observed bands for the MA monomer and dimer are reported in Table 1 and they match well with previous gas phase studies [34][35][36].…”

“…In addition, we observed a weak vibrational feature at ~1044 cm −1 after processing with 10 mC/cm 2 for all higher electron doses and after TDS (see inset in Figure 5). The position of this feature coincides with the position of the CN stretching in methylamine [36,37]. The CN stretching vibration of saturated amines is typically located in the range 1020-1250 cm −1 [38].…”

Ammonia (NH3)-assisted purification of deposits fabricated by focused electron beam-induced deposition (FEBID) has recently been proven successful for the removal of halide contaminations. Herein, we demonstrate the impact of combined NH3 and electron processing on FEBID deposits containing hydrocarbon contaminations that stem from anionic cyclopentadienyl-type ligands. For this purpose, we performed FEBID using bis(ethylcyclopentadienyl)ruthenium(II) as the precursor and subjected the resulting deposits to NH3 and electron processing, both in an environmental scanning electron microscope (ESEM) and in a surface science study under ultrahigh vacuum (UHV) conditions. The results provide evidence that nitrogen from NH3 is incorporated into the carbon content of the deposits which results in a covalent nitride material. This approach opens a perspective to combine the promising properties of carbon nitrides with respect to photocatalysis or nanosensing with the unique 3D nanoprinting capabilities of FEBID, enabling access to a novel class of tailored nanodevices.

“…We have also shown the frequency distribution for N−D modes of MA in the same figure; the average frequency of N−D modes is 2370 cm −1 . Due to aqueous solvation this mode is red shifted as compared to gas phase ND frequency . The existence of hydrogen bonds between donor and acceptor atoms is determined by the simple geometric criterion that the distance should be less than the corresponding first minimum of RDF pair.…”

We performed Car-Parrinello molecular dynamics (CPMD) simulations of deuterated aqueous solution of methylamine (MA) to investigate the structure, dynamics and time dependent vibrational spectra of water molecules in the first solvation shell. Our results show that the hydrogen bond of DOD…ND 2 is the dominant interaction between ND 2 and D 2 O as compared to the D 2 O…D 2 N. The hydrogen bond involving DOD…ND 2 has longer lifetime (2.6 ps) than both D 2 O…D 2 N (1.1 ps) and waterwater hydrogen bonds. The residence time of water molecule inside the first solvation shell of ND 2 is 5.72 ps. The vibrational spectral diffusion of water molecules in the first hydration shell of the amine nitrogen of methylamine proceeds with three time scales. A short-time relaxation originates from dynamics of amine-water hydrogen bonds without breaking (90 fs), and a slower relaxation (~1.8 ps) is due to the breaking of aminewater hydrogen bonds. Another longer time constant (~7 ps) is due to the escape dynamics of water molecules from the first hydration shell of the amine group.[a] S. Biswas
